3Com switch - interface number missing

[laffen]

Hi,

I am graphing a 3Com 7750 switch with Cacti 0.8.7b, all the graphs looks fine but they only say "3Com 7750 - Traffic - GigabitEthernet" without the switchport number. Attached 2 pictures, one of the graph and the other from config. Anything I need to add on switch or in cacti?
This is my first non-Cisco switch with Cacti, any help appreciated!

Please visit Settings->Visual. There's a setting for title length

Reinhard : sorry to say that the visual settings aint the problem.

It looks like that the 3com switch need a non-standard SNMP template.
I have the same problem with the 5500's. the 4400's are ok
I will try to figure it out somehow

Please visit "System Utilities -> View SNMP Cache", filter for that host to find the value you're seeing. Is it already truncated?

this is the snmp cache :

Host: CCS-ZWO-NS-CORE , SNMP Query: SNMP - Interface Statistics
Index: 4227625 , Field Name: ifAlias , Field Value: Naar CCS-ZWO-PK-A
OID: .1.3.6.1.2.1.31.1.1.1.18.4227625

I hope I may resurrect the thread, for I have the same issue.

cacti 0.8.7e (ubuntu 10.04 server), trying to monitor a 3com 4200g-48p switch.

Not so much to add, except that the SNMP cache has all that is needed (excerpting only one interface):

Code: Select all

Host: SW1 , SNMP Query: SNMP - Interface Statistics
Index: 4227145 , Field Name: ifAlias , Field Value:
OID: .1.3.6.1.2.1.31.1.1.1.18.4227145 

Host: SW1 , SNMP Query: SNMP - Interface Statistics
Index: 4227145 , Field Name: ifDescr , Field Value: GigabitEthernet1/0/1
OID: .1.3.6.1.2.1.2.2.1.2.4227145

Host: SW1 , SNMP Query: SNMP - Interface Statistics
Index: 4227145 , Field Name: ifHwAddr , Field Value: <mac>
OID: .1.3.6.1.2.1.2.2.1.6.4227145 

Host: SW1 , SNMP Query: SNMP - Interface Statistics
Index: 4227145 , Field Name: ifIndex , Field Value: 4227145
OID: .1.3.6.1.2.1.2.2.1.1.4227145

If I try to change the name of a data source connected to an interface, no matter if I put |query_ifName| or |query_ifDescr| I get always GigabitEthernet. |ifHwAddr| appears instead.
When I edit the data source, I see this (the indexing via ifDescr seems to work..):

thanks for any hint!

Try:
1) Check "Maximum Field Length" in Settings->Visual
2) Perform "Reapply Suggested Names" in Data Sources

Also, verify what value is specified for "Suggested Values" in Data Queries-> 'SNMP - Interface Statistics' -> Associated Graph Templates.

Another point to note is that the Suggested Naming Algorythim goes from top to bottom looking for Uniqueness. When it finds it in any set of criteria, it lands there. So, if you want to force ifAlias to work, all your interfaces need an ifAlias, or your suggested names needs to include a field that is also unique, like ifName, ifDescr or ifIndex.

Actually I fiddled with the order of the data queries suggested values, but what I got was always the same outcome (excluding the case of the template that contained "ifIndex", but that was useless to me). That's when I tried to rename directly the graph and found out that using ifDescr or ifName made no difference: I could get only 'GigabitEthernet'.

Today I followed noname's suggestion (I could have done that before but I was mislead from laffen's reply), changing the max size to 50 chars and it worked.

Noname, TheWitness, thank you both for the reply.
