PR 58974
Changing ethernet encapsulation from eth2 to snap while running traffic does not take effect until manual

PR 59599
The number of TCP Reset does not match the number of SYN Request packets after doing a Show tcp

PR 62481
ARP entries do not get updated until they timeout first (300 seconds) even though layer 3 traffic has
changed its path after a spanning tree reconfiguration due to a change in the state of a port. For these 300
seconds, the MAC is seen on the new port but the ARP entry is still learned on the old port because of
which all layer 3 traffic is dropped for 300 seconds.
Workaround: There are two workarounds:
1. Wait for 300 seconds so that the entry times out and is learned again on the new port. (recommended).
2. Clear the ARP cache using CLI command clear arp-cache.
PR 63599
debug ip packet ip-pair does not filter out all traffic based on the 'ip-pair' on the OS7000.
Workaround: 'ip-pair' only applies to IP packets. If you do not want to see ARP packets, you might want
to enter debug ip packet ether-type ip.
