SNMP packet drops Cisco 887 Router

We have 10+ 887 Routers that will drop SNMP packets every hour for exactly 5 minutes.

Every hour of the day between times ??:25 and ??:30, all of these Routers will drop SNMP packets

We have over 50 in the estate but none of the others are affected.

 

We will change nothing on the routers but they will all come back at exactly half past,

 

Any ideas where to start looking?

Re: SNMP packet drops Cisco 887 Router

Hello,

 

since you know the exact time of the problem, I would run the two EEM scripts below to capture the debug output, and then review that output, or post it here. In the scripts below, the debug starts at 1:24AM and ends at 1:31AM, since at that time it will most likely not affect any users working.

 

event manager applet DEBUG_SNMP
event timer cron cron-entry "24 1 * * *"
action 1.0 cli command "enable"
action 2.0 cli command "debug snmp detail"

 

event manager applet UNDEBUG_SNMP
event timer cron cron-entry "31 1 * * *"
action 1.0 cli command "enable"
action 2.0 cli command "no debug snmp detail"
