Hello.
I have just started setting up NetXMS, and I'm very impressed with the software.
I have been looking for monitoring software that's not "Nagios style" text configs and subprocess-plugins-for everything since quite a while.
However, I just can't find a way to solve this issue myself - hope you can help me.
NetXMS:
Version: 2.0.4
Platform: Windows, 64-bit
Database: PostgreSQL
Network:
All Cisco Catalyst.
Access switches are a mix of 3560G (IOS 12.x) and 2960X (IOS 15.x).
Core switches handling site's internal routing are 3750G (also IOS 12.x).
Everything is detected as CATALYST-GENERIC driver by NetXMS.
Problem:
Switchports that are in access mode in vlan 1, and ports that are in trunk mode and include vlan 1 in trunk vlans list are identified properly.
However, ports that do not include vlan 1 are shown as interface name "[ 0 ]" in the "Topology -> Switch forwarding database (MAC address table)" screen.
Because of that, the "Find MAC address" function falls back to showing "indirectly connected on <router trunk port>", for example.
I have verified with Wireshark that NetXMS is using the Cisco "community@123" vlan-indexing syntax.
However maybe that's part of issue - names for interfaces are retrieved for base "community" only, and it's somehow not matched to same interface index numbers in the @vlan data?
I have attached CSV dumps from the FDB screens for one of the switches - same behavior on all of them.
I'll be happy to attach a sanitized snmpwalk if you'll tell me what subtree you need.
switch13-infoFDB.csv: "Tools->Info->Switch forwarding database (FDB)"
* port 49 and 50 (SFP+ uplink trunks, including vlan 1)
* port 456 (PortGroup1 trunk, including vlan1)
* port 4 (access port in vlan1)
* no rows for other access ports
switch13-topologyFDB.csv: "Topology-> Switch forwarding database (MAC address table)"
* huge number of results for ports Gi1/0/49-50 (SFP+ uplink trunks, including vlan1)
* multiple results for port Po1 (PortGroup1 trunk, including vlan1)
* single result for port Gi1/0/4 (access port in vlan1)
* Many entries for devices connected to other access ports, showing "[ 0 ]" instead of the expected "Gi1/0/xxx".
Thank you very much!
