This chapter describes the function and displays the syntax of Local Area Transport (LAT) commands. See theAccess Services Command Reference for more infomration about defaults and usage guidelines.
To define restrictions on incoming and outgoing connections, use the access-class line configuration command. To remove the access-list number, use the no form of this command.
access-class access-list-number {in | out}| access-list-number | Specifies an integer between 1 and 199 that defines the access list. |
| in | Controls which nodes can make LAT connections into the server. |
| out | Defines the access checks made on outgoing connections. (A user who types a node name at the system prompt to initiate a LAT connection is making an outgoing connection.) |
To delete an entry from the list of queued host-initiated connections, enter the clear entry EXEC command at the system prompt.
clear entry number| number | An entry number obtained from the show entry EXEC command. |
To specify access conditions to nodes on the LAT network, use the lat access-list global configuration command. To remove a specified access list number, use the no form of this command.
lat access-list number {permit | deny} nodename| number | Specifies a number between 1 and 199 assigned to the line using the access-class line configuration command. |
| permit | Allows any matching node name to access the line. |
| deny | Denies access to any matching node name. |
| nodename | Specifies the name of the LAT node, with or without regular expression pattern matching characters, with which to compare for access. The UNIX style regular expression characters allow for pattern matching of characters and character strings in the node name. |
To enable LAT, use the lat enabled interface configuration command. To disable LAT, use the no form of this command.
lat enabledUse the lat group-list global configuration command to allow a name to be assigned to the group list. A group list is any combination of group names, numbers, or ranges. To remove the specified group list, use the no form of this command.

To define a group list for a line's outgoing user-initiated connections, use the lat out-group line configuration command.
lat out-group {groupname number range | all}| groupname | Group code name. |
| number | Group code number. You can also enter both a group code name and group code numbers. |
| range | Hyphenated range of numbers. |
| all | Range from 0 to 255. The default group code number is 0. |
To enable remote LAT modification of a line's characteristics, e.g., baud rate, use the lat remote-modification line configuration command. To disable remote LAT modification of line characteristics, use the no form of this command.
lat remote-modificationTo set the number of times that LAT retransmits a message before declaring the remote system unreachable, use the lat retransmit-limit global configuration command. To restore the default retry value, use the no form of this command.
lat retransmit-limit number| number | Number of retries; any number between 4 and 255. The default is 8 retries. |
To set the number of receive buffers that will be negotiated when the router is acting as a LAT server, use the lat server-buffers global configuration command. To return to the default of one receive buffer, use the no form of this command.
lat server-buffers receive-buffers| receive-buffers | Integer that specifies the number of receive buffers that will be negotiated. The argument can be any number between 1 and 128, and 1 is the default. |
To reenable LAT broadcast service announcements, use the lat service-announcements global configuration command. To disable the sending of LAT service announcements, use the no form of this command.
lat service-announcementsTo associate a command with a service, use the lat service autocommand global configuration command. To remove the specified autocommand, use the no form of this command.
lat service service-name autocommand command| service-name | Name of the service. |
| command | Command to be associated with the service. |
To enable inbound connections to the specified service and enable the advertisement of this service to routers on the network, use the lat service enabled global configuration command. To delete the named service, use the no form of this command.
lat service service-name enabled| service-name | Name of the service. |
To specify a group code mask to use when advertising all services for this node and to control incoming services, use the lat service-group global configuration command. To remove the group code mask specified, use the no form of this command.
lat service-group {groupname | number | range | all} [enabled | disabled]| groupname | Specifies a group code name. |
| number | Specifies a group code number. |
| range | Specifies a hyphenated range of numbers between 0 and 255. |
| all | Specifies the range from 0 to 255. |
| enabled | (Optional) Allows incremental changes to the list; that is, you can add a group code without retyping the entire command. |
| disabled | (Optional) Allows selective removal of a group code from the list. |
To set the LAT service identification for a specified service, use the lat service ident global configuration command. To remove the identification, use the no form of this command.

Use the show entry EXEC command to display the list of queued host-initiated connections to a router. You can use this command to determine which LAT hosts have queue entries for printers on routers.
show entryUse the show lat advertised EXEC command to display the LAT services a router offers to other systems running LAT on the network.
show lat advertisedUse the show lat groups EXEC command to display the groups that were defined in the Cisco IOS software using the lat group-list command.
show lat groupsUse the show lat nodes EXEC command to display information about all known LAT nodes.
show lat nodesUse the show lat traffic EXEC command to display information about traffic and resource utilization statistics on all active lines.
show lat trafficUse the show node EXEC command to display information about LAT nodes. The show node command with no further parameters shows a one-line summary of all known nodes. The show node command displays three different sets of information about a node: the node counters, the node status, or a one-line summary of the node status.
