| ring-group | Ring group number. This ring group number must match the number you have specified with the source-bridge ring-group command. The valid range is 1 through 4095. |
| interface-name | Name of the router's serial interface over which to send source-route bridged traffic. |
| mac-address | (Optional) MAC address for the interface you specify using the interface-name argument. This argument is required for nonserial interfaces. You can obtain the value of this MAC address by using the show interface command, and then scanning the display for the interface specified by interface-name. |
| lf size | (Optional) Maximum size frame to be sent to this remote peer. The router negotiates all transit routes down to this size or lower. This argument is useful in preventing timeouts in end hosts by reducing the amount of data they have to transmit in a fixed interval. The legal values for this argument are 516, 1500, 2052, 4472, 8144, 11407, and 17800 bytes. |

[local-ack] [priority]
no source-bridge remote-peer ring-group tcp ip-address
Use the source-bridge remote-peer tcp global configuration command to identify the IP address of a peer in the ring group with which to exchange source-bridge traffic using TCP. Use the no form of this command to remove a remote peer for the specified ring group.
| ring-group | Ring group number. This ring group number must match the number you have specified with the source-bridge ring-group command. The valid range is 1 through 4095. |
| ip-address | IP address of the remote peer with which the router will communicate. |
| lf size | (Optional) Maximum size frame to be sent to this remote peer. The router negotiates all transit routes down to this size or lower. Use this argument pair to prevent timeouts in end hosts by reducing the amount of data they have to transmit in a fixed interval. The valid values for this argument pair are 516, 1500, 2052, 4472, 8144, 11407, and 17800 bytes. |
| local-ack | (Optional) LLC2 sessions destined for a specific remote peer are to be locally terminated and acknowledged. Local Acknowledgment should be used for LLC2 sessions going to this remote peer. |
| priority | (Optional) Enables prioritization over a TCP network. You must specify the keyword local-ack earlier in the same source-bridge remote-peer command. The keyword priority is a prerequisite for features such as SNA class of service and SNA LU address prioritization over a TCP network. |
source-bridge remote-peer-keepalive seconds
no source-bridge remote-peer-keepalive
Use the source-bridge remote-peer-keepalive interface configuration command to enable remote-peer keepalives, which are used to verify that a remote peer is reachable. Use the no form of this command to disable the keepalive mechanism.
| seconds | Keepalive interval in seconds. The valid range is 10 through 300. The default is 30 seconds. |
[no] source-bridge ring-group ring-group
Use the source-bridge ring-group global configuration command to define or remove a ring group from the router configuration. Use the no form of this command to cancel previous assignments.
| ring-group | Ring group number. The valid range is 1 through 4095. |
[no] source-bridge route-cache
Use the source-bridge route-cache interface configuration command to enable fast switching. Use the no form of this command to disable fast switching.
[no] source-bridge route-cache cbus
Use the source-bridge route-cache cbus interface configuration command to enable autonomous switching. Use the no form of this command to disable autonomous switching.
[no] source-bridge route-cache sse
Use the source-bridge route-cache interface configuration command to enable Cisco's silicon switching engine (SSE) switching function. Use the no form of this command to disable SSE switching.
[no] source-bridge sap-80d5 dsap
Use the source-bridge sap-80d5 global configuration command to allow non-IBM hosts (attached to a router with 80d5 processing enabled) to use the standard Token Ring to Ethernet LLC2 translation instead of the nonstandard Token Ring to Ethernet 80d5 translation. This command allows you to set the translation on a per-DSAP basis. Use the no form of this command to disable this feature.
| dsap | Destination service access point (DSAP) |
[no] source-bridge spanning bridge-group
Use the source-bridge spanning interface configuration command to enable the automatic spanning tree function for a specified group of bridged interfaces. Use the no source-bridge spanning command to disable the previous assignment.
| bridge-group | Number in the range 1 through 9 that you choose to refer to a particular group of bridged interfaces. This must be the same bridge-group number as assigned in the bridge protocol ibm command. |
[no] source-bridge spanning bridge-group path-cost path-cost
Use the source-bridge spanning path-cost interface configuration command to assign a path cost for a specified interface. Use the no source-bridge spanning path-cost command to disable the previous assignment.
| bridge-group | Number in the range 1 through 9 that you choose to refer to a particular group of bridged interfaces. This must be the same bridge-group number as assigned in the bridge protocol ibm command. |
| path-cost | Path cost for the interface. The valid range is 0 through 65535. |
[no] source-bridge tcp-queue-max number
Use the source-bridge tcp-queue-max global configuration command to modify the size of the backup queue for remote source-route bridging. This backup queue determines the number of packets that can wait for transmission to a remote ring before packets start being thrown away. Use the no form of this command to return to the default value.
| number | Number of packets to hold in any single outgoing TCP queue to a remote router. The default is 100 packets. |
source-bridge transparent ring-group pseudo-ring bridge-number
tb-group [oui]
no source-bridge transparent ring-group pseudo-ring bridge-number
tb-group
Use the source-bridge transparent global configuration command to establish bridging between transparent bridging and source-route bridging. Use the no form of this command to disable a previously established link between a source-bridge ring group and a transparent bridge group.
| ring-group | Virtual ring group created by the source-bridge ring-group command. This is the source-bridge virtual ring to associate with the transparent bridge group. This ring group number must match the number you have specified with the source-bridge ring-group command. The valid range is 1 through 4095. |
| pseudo-ring | Ring number used to represent the transparent bridging domain to the source-route bridged domain. This number must be a unique number, not used by any other ring in your source-route bridged network. |
| bridge-number | Bridge number of the bridge that leads to the transparent bridging domain. |
| tb-group | Number of the transparent bridge group that you want to tie into your source-route bridged domain. The no form of this command disables this feature. |
| oui | (Optional) Organizational unique identifier. Possible values include: 90-compatible, standard, and cisco. |
