Grep for Cisco commands

To view a IOS line parser

Show parser dump

Its an excellent command to see the selected functionality of the command. we can use it just like a Grep in Unix.

For example:

R1#sh parser dump interface include queue

15 tx-queue-limit Number

15 dialer hold-queue <0-100> timeout <1-2147483>

15 dialer hold-queue <0-100>

15 dialer hold-queue

15 funi rate-queue Number Number

15 funi rate-queue tolerance svc pvc 0 strict

15 funi rate-queue tolerance svc pvc 0

15 funi rate-queue tolerance svc pvc <5-99> strict

15 funi rate-queue tolerance svc pvc <5-99>

15 funi rate-queue tolerance svc 0 strict

15 funi rate-queue tolerance svc 0

15 funi rate-queue tolerance svc <5-99> strict

15 funi rate-queue tolerance svc <5-99>

15 funi rate-queue Number Number

15 funi rate-queue tolerance svc pvc 0 strict

15 funi rate-queue tolerance svc pvc 0

15 funi rate-queue tolerance svc pvc <5-99> strict

15 funi rate-queue tolerance svc pvc <5-99>

15 funi rate-queue tolerance svc 0 strict

15 funi rate-queue tolerance svc 0

15 funi rate-queue tolerance svc <5-99> strict

15 funi rate-queue tolerance svc <5-99>

15 funi rate-queue Number Number
