- arp-aging-time
- Sets ARP aging time. This is the maximum time that a LEC will
maintain an entry in its LE_ARP cache in the absence of a verification of that
relationship. A larger aging time may result in a faster session setup
time, but may also use more memory and reacts slower to changes in network
configuration.
- Valid Values:
- An integer number of seconds in the range of 10 to 300.
- Default Value:
- 300
Example:
LEC Config> set arp-aging-time 200
- arp-cache-size
- Sets the number of entries in the ARP cache. The size of the ARP
cache limits the number of simultaneous data direct VCCs. Larger ARP
caches require more memory, but permit the client to simultaneously converse
with a larger number of destinations.
- Valid Values:
- An integer number in the range of 10 to 65535.
- Default Value:
- 5000
Example:
LEC Config> set arp-cache-size 10
- arp-queue-depth
- Sets the maximum number of queued frames per ARP cache entry. The
LEC queues frames when switching the data path from the Multicast Send VCC to
a Data Direct VCC. Frames passed to the LEC for transmission will be
discarded if the queue is full. A larger queue requires more memory,
but results in fewer discarded frames during the data path switch.
- Valid Values:
- An integer number in the range of 0 to 10.
- Default Value:
- 5
Example:
LEC Config> set arp-queue-depth 10
- arp-response-time
- Sets expected ARP response time. This value controls how frequently
an unanswered LE ARP request is retried. Larger values result in fewer
LE ARPs, which causes less traffic and possibly increase the amount of time
before a Data Direct VCC is established.
- Valid Values:
- An integer number of seconds in the range of 1 to 30.
- Default Value:
- 1 second
Example:
LEC Config> set arp-response-time 20
- auto-config
- Specifies whether this LEC uses LECS auto-config mode. Specify YES
or NO. The LEC may contact the LECS to obtain the address of its LES
and various other configuration parameters.
- Valid Values:
- If YES, then you do not have to configure the ATM address of the
LES.
If NO, then you must configure the ATM address of the LES using
the set les-atm-address command as described on page ***.
- Default Value:
- NO
Example:
LEC Config> set auto-config yes
- backup atm-net#
-
Sets the ATM net number of the backup ATM interface to be used as the ATM
interface for the LEC in case of the primary ATM interface failure.
This backup ATM interface can be concurrently functioning as the primary ATM
interface for other LECs.
- best-effort-peakrate
- Sets the Best Effort Peak Rate. Used when establishing best effort
multicast send connections.
The maximum peak rate depends on the maximum data rate of the ATM
device.
Specify an integer from 1 to the maximum peak rate in Kbps (the definition
is the maximum data rate) as follows:
- If ATM maximum data rate is 25 Mbps, the maximum peak rate is 25,000
Kbps.
- If ATM maximum data rate is 155 Mbps, the maximum peak rate is 155,000
Kbps.
- Valid Values:
- An integer number in the range of 1 - device maximum data rate.
- Default Value:
- 155000
Example:
LEC Config> set best-effort-peakrate 24000
- bus-connect-retries
- This parameter sets the maximum number of times that the LEC will attempt
to reconnect to the BUS before returning to the initial state.
- Valid Values:
- 0 - 2
- Default Value:
- 1
- connection-completion-time
- Sets the connection completion time. This is the time interval in
which data or a READY_IND message is expected from a calling party.
When a Data Direct VCC is established to the client, the LEC expects data
or a READY_IND message within this time period. The LEC will not
transmit frames over a Data Direct VCC established to it until receiving data
or a READY_IND. This parameter value controls the amount of time
which passes before the LEC issues a READY QUERY (in hopes of receiving a
READY_IND). Smaller values lead to faster response times, but also
to unnecessary transmissions.
- Valid Values:
- An integer number of seconds in the range of 1 to 10.
- Default Value:
- 4
Example:
LEC Config> set connection-completion-time 5
- control-timeout
- This parameter sets the maximum cumulative control timeout of a
request.
A current timeout value is
initialized to the value of initial-control-timeout. If a
response to a request is not received within the current timeout value, the
current timeout is multiplied by the value of the
multiplier-control-timeout and the request is reissued. Each
time the current timeout value expires, this process is repeated until the
current timeout value exceeds the value of control-timeout.
- Valid Values:
- An integer number of seconds in the range of 10 to 300.
- Default Value:
- 30
Example:
LEC Config> set control-timeout 100
- data-direct-timeout
- Specifies the timeout value for the data direct VCC. This parameter
limits the time the Data Direct VCCs are left up without the LEC having a
connection to the LES/BUS.
- Valid Values:
- 10 - 300 seconds
- Default Value:
- 30
- data-direct-vcc-mode
- Specifies whether persistent Data Direct VCC mode is enabled or
disabled. When the Data Direct VCC mode is enabled, if the LEC loses
its connection to the LES/BUS, the Data Direct VCCs are not dropped and the
reconnect timeout timer is started.
- Valid Values:
- yes or no
- Default Value:
- no
- elan-name
- Specifies name of the ELAN that the LEC wishes to join. This is the
ELAN name sent to the LECS in the configure request (if the LEC
autoconfigures) or to the LES in the join request. The LECS or LES may
return a different ELAN name in the response.
- Valid Values:
- Any character string length of 0 - 32 bytes.
- Default Value:
- Blank
| Note: | A blank name (0 length string) is valid.
|
Example:
LEC Config> set elan-name FUZZY
- esi-address
- Sets the ESI portion of the LEC's ATM address.
Specify the ESI portion (octets 13 through 19) of the LEC's ATM
address. The ESI and selector combination of the LEC must be unique
among all LAN emulation components on the device.
- Valid Values:
- Any 12 hexadecimal digits.
- Default Value:
- Burned-in ESI
Example:
set esi
Select ESI
(1) Use burned in ESI
(2) 11.22.33.44.55.66
Enter selection [1]?
- flush-timeout
- Sets the flush timeout. This is the time limit to wait to receive
the LE_FLUSH_RESPONSE after the LE_FLUSH_REQUEST has been sent before taking
recovery action. During recovery, any queued frames are dropped and a
new flush request is sent.
When switching from the multicast send to a data direct data path, the
client sends a flush request over the multicast send VCC. Until a flush
response is received, or until the path switch delay expires, frames are
queued for the destination.
- Valid Values:
- An integer number of seconds in the range of 1 to 4.
- Default Value:
- 4
Example:
LEC Config> set flush-timeout 3
- forward-delay
- Sets the forward delay. Entries in the LE ARP cache must be
periodically re-verified. The forward delay time is the maximum amount
of time a remote entry may remain in the cache during a network topology
change. Larger aging times may result in stale (invalid) entries, but
also cause less re-verification traffic.
- Valid Values:
- An integer number of seconds in the range of 4 to 30.
- Default Value:
- 15
Example:
LEC Config> set forward-delay 10
- forward-disconnect-timeout
- This parameter sets the amount of time that a LEC will wait after losing
its last Multicast Forward VCC from the BUS before returning to the initial
state. This delay permits the BUS to attempt to reconnect to the client
without returning to the initial state.
- Valid Values:
- 10 - 300 seconds
- Default Value:
- 60
- frame-size
- Sets the frame size.
The value specified for frame-size must be equal to or less than the value
specified for ATM max-frame using the ATM INTERFACE> set
max-frame command.
- Valid Values:
- 1516
4544
9234
18190
- Default Value:
- If the ELAN type is token ring, the default is 4544. If the ELAN
type is Ethernet, the default is 1516.
Example:
LEC Config> set frame-size 4544
- initial-control-timeout
- This parameter sets the value of the initial control timeout used in the
control timeout algorithm described in ***.
- Valid Values:
- 1 - 10
- Default Value:
- 5
Example:
LEC Config> set initial-control-timeout 10
- lecs-atm-address
- Specifies the ATM address of the LECS.
If the client is set to auto configure, it attempts to connect to a
LECS. If it is unable to connect to a LECS, then it may try another
LECS ATM address. The LECS ATM addresses that are tried, in order,
are:
- This configured LECS address
- Any LECS address obtained through ILMI
- The well-known LECS address defined by the ATM Forum.
No default is provided.
| Note: | This command should be entered on one command line. It is shown here
on two lines because of spacing.
|
Example:
LEC Config> set lecs-atm-address
39.84.0F.00.00.00.00.00.00.00.00.00.01.10.00.5A.00.DE.AD.01
- les-atm-address
- Sets the LES ATM address. This command may be optional or required
depending upon the setting of lecs-auto-config as described in the set
auto-config command on page ***.
- If auto-config is YES, the les-atm-address is not configurable.
- If auto-config is NO, then the les-atm-address is required.
Specify the ATM address of the LES. No default is provided.
| Note: | This command should be entered on one command line. It is shown here
on two lines because of spacing.
|
Example:
LEC Config> set les-atm-address
39.84.0F.00.00.00.00.00.00.00.00.00.01.10.00.5A.00.DE.AD.02
- mac-address
- Sets the MAC address for this LE client. You may specify
that the client use the burned-in MAC address of the ATM interface, or you may
specify a different MAC address. If you have two clients that are
bridged together, they should use different MAC addresses.
This MAC address is registered with the LES when the client joins the
ELAN.
- Valid Values:
- Any valid MAC address.
- Default Value:
- none
Example:
LEC Config> set mac-address
Use adapter address for MAC? [No]
MAC address []: 10.00.5a.00.00.01
- multicast-send-avg
- Sets the multicast send VCC average rate in Kbps. Used by the LEC
for reserving bandwidth on the VCC to the BUS. It specifies the forward
and backward sustained cell rate used when setting up a reserved bandwidth
multicast send VCC.
This parameter is only applicable when the multicast-send-type is reserved
bandwidth. If multicast-send-avg equals multicast-send-peak, then a
constant bit rate (CBR) multicast send is signalled. Otherwise, a
variable bit rate (VBR) multicast send is signalled. Multicast-send-avg
must be less than or equal to multicast-send peak.
A reserved bandwidth multicast send VCC may improve data transfer rates in
congested networks, but reserving bandwidth and not using it wastes network
resources.
When the multicast-send-type is reserved, then multicast-send-avg and
multicast-send-peak must be specified.
Example:
LEC Config> set multicast-send-avg 4000
- multicast-send-peak
- Sets the multicast send peak rate in Kbps. Used by LEC for
reserving bandwidth on the VCC to the BUS. It specifies the forward and
backward peak cell rate used when establishing a reserved bandwidth multicast
send VCC.
This parameter is only applicable when the multicast-send-type is reserved
bandwidth. If multicast-send-avg equals multicast-send-peak, then a
constant bit rate (CBR) multicast send is signalled. Otherwise, a
variable bit rate (VBR) multicast send is signalled. Multicast-send-avg
must be less than or equal to multicast-send peak.
A reserved bandwidth multicast send VCC may improve data transfer rates in
congested networks, but reserving bandwidth and not using it wastes network
resources.
When the multicast-send-type is reserved, then multicast-send-avg and
multicast-send-peak must be specified.
Example:
LEC Config> set multicast-send-peak 155
- multicast-send-type
- Sets the multicast send type. Specifies the method used by the LEC
when establishing the multicast send VCC.
If multicast-send-avg equals multicast-send-peak, then a constant bit rate
(CBR) multicast send is signalled. Otherwise, a variable bit rate (VBR)
multicast send is signalled. Multicast-send-avg must at least equal
multicast-send peak.
A reserved bandwidth multicast send VCC may improve data transfer rates in
congested networks, but reserving bandwidth and not using it wastes network
resources.
When the multicast-send-type is reserved, then multicast-send-no and
multicast-send-peak must be specified.
- Valid Values:
- Best Effort or Reserved
- Default Value:
- Best Effort
Example:
LEC Config> set multicast-send-type best-effort
- multiplier-control-timeout
- This parameter sets the value of the control timeout multiplier used in
the control timeout algorithm described on page ***.
- Valid Values:
- 2 - 5
- Default Value:
- 2
Example:
LEC Config> set multiplier-control-timeout 5
- path-switch-delay
- Sets the path switch delay.
The LEC must ensure that all frames sent through the BUS to a destination
have arrived at the destination before it can start using a Data Direct
VCC. This is accomplished using the flush protocol, or by waiting
path-switch-delay seconds after sending the last packet to the BUS.
Smaller values improve performance, but may result in out-of-order packets in
a heavily congested network.
- Valid Values:
- An integer number of seconds in the range of 1 to 8.
- Default Value:
- 6
Example:
LEC Config> set path-switch-delay 5
- reconfig-delay-min
- This parameter sets the minimum delay time when LEC returns to the initial
state. This value must be <= reconfig-delay-max.
- Valid Values:
- 1 - the value of reconfig-delay-max
- Default Value:
- 1
Example:
LEC Config> set reconfig-delay-min 5
- reconfig-delay-max
- This parameter sets the maximum delay time when LEC returns to the initial
state. This value must be >= reconfig-delay-min.
- Valid Values:
- 1 - 10
- Default Value:
- 5
Example:
LEC Config> set reconfig-delay-max 9
- retry-count
- Sets the retry count. This is maximum number of times that the LEC
retries an LE_ARP_REQUEST for a specific frame's LAN destination.
If no ARP response is received after the specified number of retries, then the
entry is purged from the LE ARP cache.
- Valid Values:
- 0, 1, or 2
- Default Value:
- 1
Example:
LEC Config> set retry-count 2
- selector
- Specifies the selector portion of the client's ATM address.
The combination of ESI and selector must be unique among all LANE components
on the device. By default, a unique selector is selected for the
configured ESI.
- Valid Values:
- Any octet, in hexadecimal, that is not in use by another LANE component
with the same ESI.
Example:
LEC Config> set selector 01
- switchback
-
Specifies whether automatic switchback is enabled or disabled.
If enabled (yes), the LEC will automatically switch back to the
primary ATM if the primary interface becomes available while the LEC is
operating over the backup ATM interface.
If disabled (no), the LEC will continue to operate over the
backup ATM interface even if the primary ATM interface becomes
available. You can force the LEC to switch back to the primary ATM
interface by issuing the switchback command from the talk
5 LEC+ command prompt.
Also if disabled (no), the LEC will switch back to the primary
ATM interface is the primary interface is available and the backup interface
fails while the LEC is operating over the backup interface.
If both the primary and backup ATM interfaces fail, the LEC will begin
operating over the interface which becomes available first.
- Valid Values:
- yes or no
- Default Value:
- no
- trace
- Enables tracing for the LEC. To perform packet tracing, three steps
are required:
- Enable packet tracing system (under ELS)
- Enable tracing on the LEC subsystem (under ELS)
- Enable packet tracing on the desired LECs (using this command).
- Valid Values:
- Yes or No
- Default Value:
- No
- unknown-count
- Sets the unknown frame count. This is the maximum number of frames
for a specific unicast MAC address or route descriptor that may be sent to the
BUS within the time specified by the unknown-time parameter. Larger
values decrease the number of discarded frames while increasing the load on
the BUS.
- Valid Values:
- An integer number of frames in the range of 1 to 255.
- Default Value:
- 10
- unknown-time
- Sets the unknown frame time. This is the time interval during which
the maximum number of frames for a specific unicast MAC address or route
descriptor (specified by the unknown-count parameter) may be sent to the
BUS. Larger values increase the number of discarded frames while
decreasing the load on the BUS.
- Valid Values:
- An integer number of seconds in the range of 1 to 60.
- Default Value:
- 1
Example:
LEC Config> set unknown-time 5
- vcc-timeout
- Sets the VCC timeout. Data direct VCCs over which no traffic has
been sent for this period of time should be released.
Valid Values: 0 to 31536000 seconds (1 year).
Default Value: 1200
| Note: | This parameter is meaningful only for SVC connections.
