4948 Switch Commands are Slow

mramirez-t
Level 1
Level 1

I have a 4948 that when running commands via SSH, is EXTREMELY SLOW.  To the point that I write commands in notepad and copy them to the switch when I'm putty'ing in.  When running anything on the switch, I can type like normal, but the command only appears on the display output slowly, character by character instead of display output showing normal as I type a command.

I've tried pinging the switch, no problem.  Below is ping results when I'm pinging the switch from 4 states away.

Pinging 10.11.128.132 with 32 bytes of data:

Also, none of the servers connected to the switch are showing any problems of network performance drag, so it's isolated to running commands.  Below is running-config.  Not sure what to look for here.  Any help's appreciated.

I have seen the same type of issue with Nexus when SNMP is enabled.  Can you disable or remove SNMP and test again?

HTH

I disabled SNMP.  Unfortunately it didn't do anything.
