I have an issue that seems so basic yet I can not make headway against it. I have had the following layout running for years:
[FGS648-01]=[SI-GTE-01]=[SI-GTE-02]=[FGS648-02]
Where the = symbols indicate a 4 port GE trunk carrying 2 VLANS via 802.1q. Suddenly all devices hanging off of FGS648-02 can not communicate with any devices on the other switches in either VLAN. The can however communicate with each other inside FGS648-02. No config changes, no reboots, FW changes, etc. happened anywhere near the time of failure.
I have tried reboots of the switches. Changed the link to a single untagged vlan. Even reduced the connection to a single GE link between SI-GTE-02 and FGS648-02. Nothing seems to resolve the issue. Has anyone else experienced this? Any suggestions on how to better diagnose or resolve?
