This chapter describes the function and displays the syntax of LAT commands. See the Access Services Command Reference publication for more information about defaults and usage guidelines.
access-class access-list-number {in | out}
no access-class number
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-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.
| number | An entry number obtained from the show entry EXEC command. |
lat access-list number {permit | deny} nodename
no lat access-list number
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.
| 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. |

| command | Command to be associated with the service. |
[no] lat service service-name enabled
