To verify multilink Frame Relay configuration, use the show frame-relay multilink command.
The following example shows output for the show frame-relay multilink command. Because a particular bundle or bundle link is not specified, information for all bundles and bundle links is displayed.
Router# show frame-relay multilink
Bundle: MFR0, state up, class A, no fragmentation
ID: Bundle-Dallas
Serial5/1, state up/up, ID: BL-Dallas-1
Serial5/3, state up/add-sent, ID: BL-Dallas-3
Bundle: MFR1, state down, class B, fragmentation
ID: Bundle-NewYork#1
Serial3/0, state up/up, ID: BL-NewYork-1
Serial3/2, state admin-down/idle, ID: BL-NewYork-2
The following example shows output for the show frame-relay multilink command with the serial number option. It displays information about the specified bundle link.
Router# show frame-relay multilink serial3/2
Bundle links :
Serial3/2, HW state :Administratively down, Protocol state :Down_idle, LID :Serial3/2
Bundle interface = MFR0, BID = MFR0
The following examples show output for the show frame-relay multilink command with the serial number and detail options. Detailed information about the specified bundle links is displayed. The first example shows a bundle link in the "idle" state. The second example shows a bundle link in the "up" state.
Router# show frame-relay multilink serial3 detail
