We have a Cisco SLM2024 router, firmware version 22.214.171.124, boot version 1.0.1, hardware version 00.03.00. We have 3 VLAN's setup on this switch using vlan tagging that carries high traffic voip.
We have recently been performing some packet traces trying to determine some problems on our voip network that is connected via this switch and discovered that intermittantly some packets that are being delivered to the wrong port on the switch - randomly. We verified this via a wireshark capture whereby the 3 ports we are monitoring have 3 connections with different IP addresses however packets that should have gone to an alternate port with the correct IP address randomly shows up on these ports.
I'm not sure how the packets are accidentally leaking to another port and wondering if anyone else has noticed this problem?
Our setup we have 3 VLAN's with 3 different ID tag #'s. The id tag numbers are assigned to the PVID for the respective ports however the ports are maked as untagged. The main ISP connected port that serves us the VLAN's is tagged for all 3 VLAN's.
