Recommended: "7.2.02d" firmware for Layer 3 FCX stack

In our 6-member Layer 3 FCX stack that routes 7 VLANs and sees about 150 MAC addresses, some IPs intermittently became unreachable via Layer 3 after the switches were up for a while.  Even saw cases where ICMP worked and TCP didn't.

We upgraded to 7.2.02d a week ago, and have not seen the problem since.  I'm hoping it resulted from the following bug fixed in "d":

Defect ID: DEFECT000357433
Technical Severity: High
Summary: Layer 3 traffic sometimes does not get forwarded on an FCX stack.
Symptom: IP Traffic is not forwarded on an FCX stack’s member units.
Workaround: Clearing the MAC or ARP tables temporarily resolves the problem.
Probability: Low
Feature: FCX Layer 3 Forwarding - IPV4
Function: Data Forwarding (IPV4)
Reported In Release: FI 07.2.02
Service Request ID: 601967

Especially if you are seeing similar issues, I highly recommend trying the upgrade.

that's correct. a lot of stacking related bugs are fixed in 7.2.02D.

7.2.02D also has a couple of POE related fixes, so its a good code to be on.

Unless you're planning to use PVLANs :-(

There is more details in the other thread started by me.

Hi.

We have good expereince with v7202d on FCX stacks.

But we encountered issues during upgrading from v7100a to v7202d, units not syncing the new firmware file and boot preference on all units.

Be aware of the correct stack member priority configuration when using a 2-unit stack.

Cheers

Karl

Karl,

For what it's worth, syncing the new firmware from our active stack unit (7.2.02d) to the others (7.2.00a) was a manual process for me today.  I repeated

copy flash flash unit-id-pri 2

for each member destination unit-number.
