Monitoring Server NICs

remilner82 · Post by **remilner82** » Tue Aug 31, 2010 9:25 am

Hello,

We have about 30-40 Dell PE Servers all with dual port Broadcom NIC's. Is it possible to monitor both ports so that if one interface on the server goes down, we can be alerted to the issue?

Any help would be greatly appreciated.

Each card has 2 IP interfaces and 2 different IP addresses? Then you may use simple Ping tests to check each interface.

Hi Alex,

The cards are teamed so they share the same IP address. I need to know if one card fails or the links drop for any reason.

Then HostMonitor does not have any way to check this.. unless driver and some special software from manufacturer offers such option.

E.g. if there is some SNMP agent comes with this network card, it probably provides such information. Then you may use SNMP Get test method to check card status.
As I see Broadcom 5709S offers such option
http://www.broadcom.com/collateral/pb/5709S-PB02-R.pdf

Please check software that comes with your network card. Probably there is SNMP agent (and may be its already installed and running). Also I think it should come with MIB file that can be compiled by our MIB Browser.
Actually you can setup test without using MIB file and MIB Browser, its just more convenient way to work with agent.

Thanks for the info Alex. I needed to install the SNMP sub agent which is available as a download from the Broadcom site. I have managed to get the necessary information from the following OID (which is named as btpMemberState):

1.3.6.1.4.1.4413.1.2.1.2.2.1.6.1.1 (NIC 1)
1.3.6.1.4.1.4413.1.2.1.2.2.1.6.1.2 (NIC 2)

At the moment, they are returning values but there is no documentation anywhere of what the values mean (e.g. does 1=OK, 2=Error etc). I have raised a new support ticket with Broadcom, so I will post back when they have given any information on this.

Do you have any MIB files that come with SNMP Agent software?
I think you need baspCfg.mib file. there should be description of possible statuses

Hi Alex,

You are right, there is a value description within the MIB file. However, I am now using the adptinfo.mib file, as there is an entry called "ifLinkStatus" which has the information that I require. It returns a value of either 1 (Link-up) or 2 (Link-fail).

I have therefore created two tests, and tweaked the reply value to say Link-up or Link-fail depending on the suggestedreply value.

Many thanks for your help on this Alex. Hopefully someone else will find this information useful.
