Dear All,
is there any command to see bdp uptime/downtime log for a certain period, like for last 7 days or so.
i need to see for last 7 days how many times bgp got down and what time are those happened.

if you configured "bgp log-neighbor-changes" under bgp, you should see it in the logs. If it is not configured, please do so, so it can help you next time in troubleshooting....

Hi Parvez,
You can use below methods, to get details about BGP neighbor state changes
1. #show log | in BGP (from router console)
2. #Depend on syslog server to which you are logging
3. Or use BGP SNMP event notifications. For this you can use SNMP server.
Thanks,

Hi ,
One other option is to get an EEM script that will notify you or send the logs in a file whenever BGP goes down.
Thanks

Hi Parvez ,
Here is the EEM script that i have written for my BGP neighbor going down.
event manager applet BGP_Notify
event syslog pattern "%BGP-5-ADJCHANGE: neighbor 20.0.0.2 Down"
action 1.0 cli command "enable"
action 2.0 cli command "show clock | append bootdisk:bgplog.txt"
action 3.0 syslog msg "BGP Down"
So now look at the logs in my router.
when i shut down my BGP neighor , EEM triggers and it alsonotify that BGP down.
TAM(config)#router bgp 1
TAM(config-router)#nei 20.0.0.2 shut
TAM(config-router)#
*Nov 14 13:19:15.894: %BGP-5-ADJCHANGE: neighbor 20.0.0.2 Down Admin. shutdown
*Nov 14 13:19:15.894: %BGP_SESSION-5-ADJCHANGE: neighbor 20.0.0.2 IPv4 Unicast topology base removed from session Admin. shutdown
*Nov 14 13:19:16.322: %HA_EM-6-LOG: BGP_Notify: BGP Down
TAM(config-router)#
now look at the file that is created in bootdisk now
TAM#dir bootdisk:
Directory of bootdisk:/
1 -rw- 249462 Jul 16 2012 04:38:14 +00:00 config-16jul
2 -rw- 249382 Jul 6 2012 13:46:24 +00:00 config
3 -rw- 72 Aug 27 2012 11:16:28 +00:00 BGP.TXT
4 -rw- 36 Nov 14 2012 13:13:58 +00:00 bgplog.txt
5 -rw- 36 Nov 14 2012 13:19:16 +00:00 bgpdown.txt <---- ( same name what i have configured )
lets check the file now.
TAM#more bootdisk:bgpdown.txt
*13:19:16.010 UTC Wed Nov 14 2012 <---- shows that time when it went down
Tried one more time and now my file has two entries
TAM(config-router)#nei 20.0.0.2 shut
TAM(config-router)#
*Nov 14 13:22:34.906: %BGP-5-ADJCHANGE: neighbor 20.0.0.2 Down Admin. shutdown
*Nov 14 13:22:34.906: %BGP_SESSION-5-ADJCHANGE: neighbor 20.0.0.2 IPv4 Unicast topology base removed from session Admin. shutdown
*Nov 14 13:22:35.130: %HA_EM-6-LOG: BGP_Notify: BGP Down
TAM(config-router)#
TAM(config-router)#exit
TAM(config)#exit
TAM#more
*Nov 14 13:22:44.758: %SYS-5-CONFIG_I: Configured from console by console bootdisk:bgpdo
TAM#more bootdisk:bgpdown.txt
*13:19:16.010 UTC Wed Nov 14 2012
*13:22:34.918 UTC Wed Nov 14 2012 <------
