An ATM address is composed of:
ATM routing is based on the Network Prefix plus the End System Identifier.
This adapter MAC address is called the universally administered or the burned-in address.
Using locally administered ESIs instead of allowing the system to default to a universally administered (burned-in) ESI makes problem determination easier.
In both cases, you can then choose a locally unique selector to ensure that your address is valid. You will have 200 Selector values for each ESI that can be assigned to make unique ATM End System Addresses. Addresses will be registered with the switch, which will reject the registration if the ATM address is not unique.
This page defines the locally administered End System Identifier (ESI) component of the ATM End System Address used by an ATM device. If you want to use locally administered ESIs, choose any combination of 12 hexadecimal digits as your ESI.
You may repeat this step up to 16 times in order to associate up to 16 different ESIs with this physical interface. Ensure that you write down all ESIs that you enter, as you will need them later in the configuration process.
It is suggested that you enter locally administered ESIs instead of allowing the system to default to a universally administered ESI. Using locally administered ESIs makes problem determination easier.

Valid Values: An integer in the range of 16 - 65535
Default Value: 9234
This parameter sets defaults and upper bounds for VCC traffic parameters of components, such as LAN Emulation and Classical IP, created on this ATM interface. For example, the parameter sets the default peak cell rate for best effort VCCs initiated by the components. The parameter also sets an upper bound on the cell rates that can be configured for any individual VCC, as well as setting an upper bound on the amount of reserved bandwidth that the components can accept.
The units of the parameter are Mbps. In general, the Default of this parameter should be suitable for most configurations. As an example of a situation where adjusting the value of this parameter could be useful, consider a configuration where the majority of the stations use 25 Mbps adapters. In this case, it might be desirable to limit any individual VCC to 25 Mbps in order to reduce the likelihood of overruns due to speed mismatches. Note that this parameter will not affect instantaneous transmission rates, nor will it constrain cumulative throughput across all VCCs.
Valid Values:
25

A LEC provides the intermediate layer between the connectionless application-to-MAC layer and the connection-oriented layer of ATM. A LEC is identified by a combination of ATM address and MAC address. A LEC resolves LAN addresses to ATM addresses and filters incoming unicast and multicast traffic to ensure that it is destined for the end system represented by the LEC.
LECs may be members of one or more ELANs. Membership in an ELAN does not depend on physical location, and an end user may belong to more than one emulated LAN, but clients cannot communicate across LAN boundaries.
If you do not use the adapter address as the LE client's ESI address, enter the locally administered ESI for the LE client ESI address. If you do not select the adapter address, then only those locally administered ESI addresses that have been configured and enabled for this ATM interface are valid.

The LECS provides configuration services for the LAN Emulation Service. The LECS assigns clients to a particular emulated LAN service by giving the client the ATM address of the LAN Emulation Server (LES). The LECS makes assignment based on ATM address or the identity of a LAN destination that it represents. The LECS uses assignment policy values to help make assignments. Each policy value represents an association between a possible value in a configuration request coming from a client and a LES.
The LECS reduces the network management burden by serving as a central repository for configuration data, minimizing configuration of clients.
After the LECS has determined the appropriate LEC to LES assignment pair, the LECS returns to the client configuration data that includes the following information: LES ATM address, ELAN type, Max Frame Size, and ELAN name, as well as any user-defined parameters. The LECS provides configuration services for the LAN Emulation Service.
The ADD option adds a LECS to your ATM network. It adds a LECS to the static configuration of the MSS Server.
Select a value that has not already been assigned to a LAN Emulation component. The range of valid selector values is the same that was specified for the ATM device interface.
This value will default to 0 unless a selector value of 0 has already been used for the ESI you specified in step 1.
The following parameters should assume Defaults unless you are tuning an operational network.
At the sending side of the network, data frames are broken into very short blocks called cells. At the destination side of the network, the cells are reassembled into data frames.
You can specify the traffic characteristics of the cells.
If you enable this parameter, Best Effort Configuration Direct VCCs will be rejected if the Peak Cell Rate exceeds the line speed of the LECS ATM device.
Important Note: Accepting Best Effort VCCs with Peak Cell Rates that exceed the line speed can result in poor performance due to excessive retransmissions. However, rejecting the Best Effort VCCs can result in interoperability problems that may cause traffic on your network to halt.
This rate is the maximum acceptable Sustained Cell Rate for the Configuration Direct VCC. The chosen rate is used for both forward and backward directions on the Configuration Direct VCC.

TLVs are optional parameters that may be returned to all clients assigned to the selected ELAN.
An ELAN can be configured with a variable number of Type, Length, or Value (TLV) descriptors. TLVs provide a method to configure the client with optional or user-defined parameters. TLVs are defined on an ELAN basis. Thus, the same set of TLVs is returned to all clients that are assigned to a particular ELAN.
For example, a user-defined TLV would be useful in the following situation:
When ELANs are spread over a large geographic area, the default timeout values for LECs may be insufficient. These timeouts can be controlled for all LECs on the ELAN by specifying their value in a TLV at the LECS.

Packet tracing is a troubleshooting tool that allows you to see what is actually being transmitted between different components of the network. This information, along with Event Logging System messages, allows you to diagnose problems or provide trace information to network support. If you are having trouble as the result of information flow (as opposed to network up/down crashes), you can use packet tracing to figure out what is going on.
You can specify an ATM address filter for packet tracing. For each VCC, if the ATM address of the entity at the other end of the VCC matches the ATM-address-value on all bits set by the ATM-address-mask, then packet tracing may be performed on that VCC.
The ATM address value is compared with the bit string result of logically ANDing the ATM address trace filter mask that you specify and the calling party's ATM address. If the resulting bit string and the ATM address filter value match, and if packet tracing is enabled, then traffic over that VCC will be traced.
In order to see the packet traces, use the 'view' facility of the Event Logging System (ELS) (use the operator console in Talk5 of the Command Line Interface).
Example:
Trace all packets over all VCCs whose calling party ATM addresses contains the following network prefix.
Value: 0x3999999999999900009999070700000000000000
Mask: 0xFFFFFFFFFFFFFFFFFFFFFFFFFF00000000000000

ATM address of Pkt(2): 0x3999999999999911119999070710005A820D4401
Packet 1 will be traced and Packet 2 will not be traced.
Enter the ATM Address Trace Filter Mask value.
This value can be any 20-byte hexadecimal string. It is not required to be an actual ATM address.
For packet tracing to occur, you must enable it in the ELS subsystem. Enter a buffer size and number of bytes to be traced. Then issue 'trace subsystem lecs'.

This option defines static entries for the Broadcast Manager (BCM).
Broadcast Management is an enhancement of the BUS function in LAN Emulation. Without Broadcast Management, every broadcast and multicast frame sent to the BUS is forwarded to all LAN Emulation clients on the ELAN. Also, clients that are serving as proxy for other stations then forward the broadcast frame on to other LAN segments.
When Broadcast Management is enabled, BCM attempts to transform broadcast frames into unicast frames and sends them only to interested LAN Emulation clients and end stations. Reduced broadcast traffic results in fewer nuisance frames sent to clients and an overall reduction in network utilization.
You can statically configure a LEC to receive all managed broadcasts for a BCM managed protocol.
When enabled for IP, Broadcast Manager scans all IP ARP requests and replies to learn the location of IP addresses in the subnet containing the ELAN. Broadcast Manager then takes each broadcast ARP request frame and forwards it as a unicast frame directly to the LEC representing the IP station.
When enabled for IPX, Broadcast Manager dynamically identifies the set of IPX routers and servers based on IPX Routing Information Protocol and Service Advertising Protocol advertisement transmissions and forwards these RIP/SAP advertisements only to other IPX routers and servers. You may want to configure a network management station to monitor RIP/SAP broadcasts in order to discover the IPX topology. You accomplish this by configuring the network management station as a static target for IPX broadcasts. This causes the station to receive RIP/SAP broadcasts.
Any device that requires reception of IPX advertisements that does not transmit advertisements must be configured as a Static Target. An example would be a station running software that discovers IPX network topology by monitoring IPX advertisements. Broadcast Manager for IPX is not aware of this "quiet" station without a Static Target definition of its MAC address and the address of the representing LEC.
A Static Target also can be used effectively when many IPX Routers and Servers are represented by a single LEC. By configuring a Static Target with the ATM address of the LEC, but with a broadcast MAC address of all Fs, all IPX Routers and Servers behind the LEC receive a single broadcast advertisement rather than multiple unicast advertisements.

You can select the adapter address as the ESI. If you do not use the adapter address, you must choose an ESI for this interface. You must have added the ESIs before you can choose one.
This action sets the MAC address for this LE client. You can specify that the client use the adapter's MAC address, or you can specify a different MAC address. If you have two clients that are bridged together, then they both cannot use the same MAC address.
The selector byte is the value to be used as Selector field component of local ATM address used when calling the LECS.
Valid Values: any octet in hexadecimal, 00 to FF, that has not already been assigned to the LECS ATM device. The combination of LECS ESI and LECS selector must be unique among all LAN Emulation components using the LECS ATM device.
This value must be equal to or less than the value specified for ATM Maximum frame size using the Adapter Interface Set option.
This name specifies name of the ELAN that the LEC wishes to join.
Valid Values: a character string of length 0-32 bytes.
Default Value: blank
Note: A blank name (0 length string) is valid. ELAN name is not a required parameter.
This sets the timeout period used for timing out most request/response control frame interactions.
Valid Values: an integer number of seconds in the range 10 to 300.
Default Value: 120 seconds
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.
Valid Values: an integer number in the range 1 to 10.
Default Value: 1
This is the time interval during which the maximum number of frames for a specific unicast MAC address or route descriptor (specified by the Maximum unknown frame count parameter) may be sent to the Broadcast and Unknown Server (BUS).
Valid Values: an integer number of seconds in the range 0 to 60.
Default Value: 1 second
This Sets the VCC timeout. Data direct VCCs that are idle this long should be released.
Valid Values: specify an integer number in the range 0 seconds to 1 year.
Default Value: 1200 seconds = 20 minutes
Note: This parameter is meaningful only for SVC connections.
This sets the maximum number of times that the LEC retries an LE_ARP_REQUEST for a specific frame's LAN destination.
Valid Values: an integer number in the range 0 to 2.
Default Value: 1
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.
Valid Values: an integer number of seconds in the range 10 to 300.
Default Value: 300 seconds
This is the maximum time that a LEC maintains an LE_ARP cache entry for a non-local MAC address in the absence of a verification of that relationship, as long as the configuration has not changed.
Valid Values: an integer number of seconds in the range 4 to 30.
Default Value: 15 seconds
This parameter sets expected ARP response time.
Valid Values: an integer number of seconds in the range 1 to 30.
Default Value: 1 second
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.
Valid Values: an integer number of seconds in the range 1 to 4.
Default Value: 4
This is the time that the LEC has to wait, after sending something to the BUS, before it assumes that the frame has reached the destination. The LEC can then send frames directly to the destination on a different path.
Note: The path switch delay may be used to bypass the flush protocol.
Valid Values: an integer number of seconds in the range 1 to 8.
Default Value: 6 seconds
This parameter specifies the method used by the LEC when establishing the multicast send VCC.
Valid Values: Best-Effort or Reserved.
Default Value: Best-Effort.
Note: These traffic parameters are similar to those for LES-BUS (LAN Emulation Services - Broadcast and Unknown Server).
This value is the multicast send VCC average rate in Kbps. It is used by the LEC for reserving bandwidth on the VCC to the BUS. It specifies the average rate to be used for forward and backward sustained cell rate to be requested by the LEC when it is setting up multicast send VCCs and using reserved bandwidth connections.
Both the setting and the default depend on the parameter specified for Multicast send VCC type.
This value is the Multicast send VCC peak rate in Kbps and is used by the LEC for reserving bandwidth on the VCC to the BUS. It specifies the peak rate to be used for the forward and backward sustained cell rate to be requested by LEC when it is setting up the multicast send VCC and using reserved bandwidth connections.
Both the setting and the default depend on the parameter specified for Multicast send VCC type.
This value sets the connection completion timer. This is the time interval in which data or a READY_IND message is expected from a calling party.
Valid Values: an integer number of seconds in the range 1 to 10.
Default Value: 4 seconds
This value sets the maximum number of queued frames per ARP cache entry.
Valid Values: an integer number in the range 0 to 10.
Default Value: 5
This value sets the number of entries in the ARP cache.
Valid Values: an integer number in the range 10 to 1000.
Default Value: 10
This value is used when establishing best effort multicast send connections.
The maximum peak rate depends on the line speed of the ATM device.
Valid Values: an integer from 1 to the maximum peak rate in cells per seconds as follows:
If ATM line speed is 155 Mbps, the maximum peak rate is 155000 Kbps.
Default Value: 25000 cells per second
This value specifies how many times the client will retry the configuration phase of joining an ELAN (in the event of failure.)
Valid Values: an integer number in the range 0 to 5.
Default Value: 3
This parameter sets packet trace for the LEC.
Default Value: packet trace is disabled
