Monitoring BGP

Tavares_Belmont — Tue, 26 May 2015 01:06:00 GMT

Hello guys!

We are trying to monitor a BGP session in a SW extreme(X450). We use the command "snmpwalk" to validate the information regarding the OID of BGP, where it informs that there are 5 sessions. When we try to do a "snmpwalk" in a session more specific, it returns an error stating that the OID do not hesitate.
Any suggestion? XOS version is 15.2.1.5

Picture error bellow...

Tavares,

Do we experience the same error when executing a SNMP get locally on the switch? The command would be "show snmp get 1.3.6.1.2.1.15.3.1.2.a.b.c.d" where a.b.c.d is the IP address of the BGP peer.

Hi Andrew,

We have the same situation. when we put the command below, the error is the same.

show snmp get 1.3.6.1.2.1.15.3.1.2.a.b.c.d
mib_2.15.3.1.2.x.x.x.x = NO_SUCH_IINSTANCE_EXCEPTION

we realeased that the msg appear in zabbix too.

Tavares,

This issue will require a deeper level of investigation. It would be recommended to call into GTAC and open a ticket.

yes i see,

but i found this command "configure snmpv3 add mib-view "name" subtree "oid" type excluded | included...

Its possible add subtree and use via snmv3? The website bellow show possibles OIDS and respective funcions too, on extreme switch juts works "show snmp get 1.3.6.1.2.1.15.2.0" = local AS and 1.0 BGP version, i created a ticket on TAC but until now anyone reply.

Tavares,

I do not believe the "configure snmpv3 add mib-view" command will assist in this issue. Were you able to get a reply on the open ticket?

Hello,

They told me that usually similar problems with this are usually only resolved with external intervention of the development area because the extreme not have these MIBs implemented in software, they closed the ticket on the grounds that other monitoring systems as Rigdline and Netsght work properly.

Thank you guys!

"I've been in contact with the team and sustaining new tests were conducted regarding the monitoring via SNMP of BGP peers."

Example:

Note:

The MIB will respond values from 1 to 6 and will be manager function to convert it to the corresponding string:

Values 1: idle

2: connect

3: active

4: OpenSent

5: OpenConfirm

6: established

The device can get that information based on "strings".

summitX460.8 # show snmp get-next 1.3.6.1.2.1.15.3.1.2 mib_2.15.3.1.2.10.10.10.1 = 6 (established)

Object bgpPeerState

Main OID 1.3.6.1.2.1.15.3.1.2
