Syntax:
Use the frame command to set the NetWare IPX encapsulation
type. The command options differ depending on the type of LEC
(Token-Ring or Ethernet). For Token-Ring LECs, enter one of the
following:
| Option | Description | Syntax |
|---|---|---|
| Token-Ring using MSB | Uses the standard 802.2 IPX header with the noncanonical Token-Ring address bit ordering (MSB). | frame token-ring msb |
| Token-Ring using LSB | Uses the 802.2 IPX header with the canonical address bit ordering (LSB). | frame token-ring lsb |
| Token-Ring with 802.2 SNAP using MSB | Uses the 802.2 format with a SNAP header and noncanonical address bit ordering. This encapsulation is used primarily in bridging environments. | frame token-ring_snap msb |
| Token-Ring with 802.2 SNAP using LSB | Uses the 802.2 format with a SNAP header and canonical address bit ordering. | frame token-ring_snap lsb |
| Ethernet 2.0 | Uses Ethernet version 2.0 protocol 81-37. | frame ethernet_II |
| Ethernet 802.2 | Uses Ethernet 802.3 with 802.2 SA E0. | frame ethernet_8022 |
| Ethernet 802.3 | Uses Ethernet 802.3 without any 802.2 header. | frame ethernet_802.3 |
| Ethernet SNAP | Uses 802.3, 802.2 with SNAP PID 00-00-00-81-37. | frame ethernet_SNAP |
Syntax:
| Note: | The frame command cannot be used in the network configuration process to set the IPX encapsulation unless the interface has been configured with IPX. |
The IPX encapsulation can also be set in the IPX configuration environment. Refer to the chapter entitled "Configuring and Monitoring IPX" in the Protocol Configuration and Monitoring Reference for details.
Example:
frame token_ring msb
Use the IP-encapsulation command to select Ethernet (Ethernet type X'0800'), IEEE 802.3 (Ethernet 802.3 with SNAP), or both.
The option both enables the2216 to use Ethernet encapsulation to transmit to hosts that have Ethernet encapsulation and to use IEEE 802.3 encapsulation to transmit to hosts that have IEEE 802.3 encapsulation. If your Ethernet LAN includes some hosts that use one type of encapsulation and some that use the other, entering both enables all of them to communicate.
The option both applies only to unicast frames. If you enter both, you are prompted to enter either ethernet or ieee-802.3 for broadcast and multicast frames.
Syntax:
Example:
Ethernet Forum Compliant LEC Config> ip-encapsulation both How would you like IP broadcast/multicast frames to be sent (ETHER/IEEE-802.3) [ETHER]?
Use the list command to list the LE client configuration.
Syntax:
Logical Link Control can be thought of as a "sub-protocol". It is not accessed directly from either the Talk 6 (configuration) or the Talk 5 (console) environment. Instead, it is accessed from the Token Ring LEC configuration menu by entering an LLC command.
Use the llc command to access the LLC Config> prompt. See"LLC Configuration Commands" for more information.
Syntax:
Use the qos-configuration command to get you to the LEC QoS Config> prompt from which you can configure Quality of Service as described in LE Client QoS Configuration Commands in Using and Configuring Features.
Syntax:
Use the RIF-Timer command to set the maximum amount of time that information in the RIF is maintained before it is refreshed. Range is 0 to 4096. The default is 120 seconds.
Syntax:
Example:
rif-timer 100
Use the set command to set LE Client parameters.
Syntax:
Example:
LEC Config> set arp-aging-time 200
Example:
LEC Config> set arp-cache-size 10
Example:
LEC Config> set arp-queue-depth 10
LEC Config> set arp-response-time 20
If NO, then you must configure the ATM address of the LES using the set les-atm-address command as described on page ***.
Example:
LEC Config> set auto-config yes
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:
Example:
LEC Config> set best-effort-peakrate 24000
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.
Example:
LEC Config> set connection-completion-time 5
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.
Example:
LEC Config> set control-timeout 100
| Note: | A blank name (0 length string) is valid. |
Example:
LEC Config> set elan-name FUZZY
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.
Example:
set esi
Select ESI
(1) Use burned in ESI
(2) 11.22.33.44.55.66
Enter selection [1]?
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.
Example:
LEC Config> set flush-timeout 3
Example:
LEC Config> set forward-delay 10
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 as described on page ***.
4544
9234
18190
Example:
LEC Config> set frame-size 4544
Example:
LEC Config> set initial-control-timeout 10
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:
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
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
If you have two clients and each client has IPv6 configured, these clients should use different MAC addresses.
This MAC address is registered with the LES when the client joins the ELAN.
Example:
LEC Config> set mac-address
Use adapter address for MAC? [No]
MAC address []: 10.00.5a.00.00.01
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
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.
LEC Config> set multicast-send-peak 155
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.
Example:
LEC Config> set multicast-send-type best-effort
Example:
LEC Config> set multiplier-control-timeout 5
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.
Example:
LEC Config> set path-switch-delay 5
Example:
LEC Config> set reconfig-delay-min 5
Example:
LEC Config> set reconfig-delay-max 9
Example:
LEC Config> set retry-count 2
Example:
LEC Config> set selector 01
Example:
Token Ring LEC config>set trace Trace packets on the LEC? [No]?yes
Example:
LEC Config> set unknown-time 5
Valid Values: 0 to 31536000 seconds (1 year).
Default Value: 1200
| Note: | This parameter is meaningful only for SVC connections. |
Example:
LEC Config> set vcc-timeout 1000
Use the source-routing command to enable or disable end station source-routing. Source routing is the process by which end stations determine the source route to use to cross source routing bridges. Source routing allows the IP, IPX, and AppleTalk Phase 2 protocols to reach nodes on the other side of the source route bridge.
This function of the device is not changed whether source routing is enabled or disabled. The default setting is enabled.
Some stations cannot properly receive frames with Source Routing RIF on them. This is especially common among NetWare drivers. Disabling source routing in this situation will allow you to communicate with these stations.
Source routing should be enabled only if there are source-routing bridges on this ring through which you want to bridge IP, IPX, and AppleTalk Phase 2 packets. Source routing must also be enabled so that LLC test response messages can be returned.
Syntax:
Example:
source-routing disable
