To verify DLSw configuration, perform these tasks:
Verify the configuration of LLC type 2 properties on a Fast Ethernet interface.
From the J-Web interface, select Configuration>View and Edit>View Configuration Text. Alternatively, from configuration mode in the CLI, enter the show interfaces fe-3/0/0 command.
- user@host# show interfaces fe-3/0/0
- fe-3/0/0 {
-
- unit 0 {
-
- family inet{
-
- address 172.5.20.1/24;
- }
- family llc2}
- }
- }
Verify that the output shows the intended LLC type 2 configuration.
Verify DLSw capabilities of remote DLSw peers.
From the CLI, enter the show dlsw capabilities command.
