3Com MSR 50, MSR 30 manual X25 hunt-group, 445

445

Description Use the x25 default-protocolcommand to set the default upper-layer protocol of X.25 for the X.25 interface.

Use the undo x25 default-protocolcommand to restore the default.

By default, no upper-layer protocol is specified.

During X.25 SVC setup, the called device will check the call user data field of X.25 call request packet. If it is an unidentifiable one, the called device will deny the setup of the call connection. However, a user can specify a default upper-layer protocol carried over X.25. When X.25 receives a call with unknown CUD, the call can be treated based on the default upper-layer protocol specified by a user.

Example # Set the default upper-layer protocol over the X.25 interface Serial2/0 to IP.

Parameter hunt-group-name: Name of a hunt group, a string of 1 to 30 characters.

round-robin: Selects call channel using cyclic selection policy.

vc-number: Selects call channel using the policy of computing available logical channel.

Description Use the x25 hunt-groupcommand to create or enter an X.25 hunt group.

Use the undo x25 hunt-groupcommand to delete the specified X.25 hunt group.

X.25 hunt group supports two call channel selection policies: round-robinmode and vc-numbermode, and a hunt group only uses one channel selection policy. The round-robinmode will select next interface or XOT channel inside hunt group for each call request using cyclic selection method. The vc-numbermode will select the interface with the most idle-logical channels in hunt group for each call request.

A hunt group can have 10 interfaces or XOT channels at most, and it can select the available channels between interface and XOT channel.

XOT channel cannot join the hunt group that adopts the vc-numberselection policy.
