Inconsistent results for Extreme switches when in stack
Closed this issue · 1 comments
I'm trying to use this script to extract port to vlan information on some Extreme switches I have.
I have a stack of 4 x X440 extreme switches which have the following ports tagged in a vlan:
1:45
1:48
3:48
The Interface vlan id is: 1000034.
When running the following code:
print_r($snmpHost->useExtreme_Vlan()->getTaggedPortsForVlan(1000034));
We get an array returned with 96 entries indexed from 1001 - 1048 and 2001 - 2048 all of them set to false. The first issues is there should be 192 ports, but I think the ordering is also incorrect as the first 92 ports should have some tagged vlans.
If I manually walk the OID I can see data which looks more correct, e.g.
$ snmpwalk -v 2c -c <communityString> <IP> .1.3.6.1.4.1.1916.1.2.6.1.1.1.1000034
SNMPv2-SMI::enterprises.1916.1.2.6.1.1.1.1000034.1 = Hex-STRING: 00 00 00 00 00 09 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
SNMPv2-SMI::enterprises.1916.1.2.6.1.1.1.1000034.2 = Hex-STRING: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
SNMPv2-SMI::enterprises.1916.1.2.6.1.1.1.1000034.3 = Hex-STRING: 00 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
SNMPv2-SMI::enterprises.1916.1.2.6.1.1.1.1000034.4 = Hex-STRING: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
I therefore suspect that function opaqueTaggedPorts() which in turn calls subOidWalk() isn't returning all the data. I've tried
Any help or advice much appreciated.

Closing as this is stale. If it's an issue you want me to look at, please reopen but I may need snmp read access to a suitable device for testing.
