I periodically do a little with Cisco devices, but not very often. I used to have a filtering command that was pretty handy. It'd go something like:

show run | include interface next 5

That'd display every line of output that had "interface" and the next 5 lines after the line that had "interface" in it.

Today I upgraded some new switches (3750X) to IOS 15.2(4)E4. And that "next" command switch doesn't seem to work. If I just do:

show run | include interface

That works by displaying only the line with "interface" in the line. But if I add "next 5", it returns no results. Also, the "prev" command switch doesn't work either.

Any help is appreciated.

    Have you looked in the release notes? – Ron Trunk Jun 20 '17 at 20:36
  • @RonTrunk I had not, but now I have. I also checked release notes for 15.2(3)E and 15.2(2)E. I didn't find anything about the include command switch. – user3271408 Jun 21 '17 at 0:25

The answer is that prev and next were removed in IOS 15. The closest command they have to that functionality is the section command:

Show run all | section interface
