A valid recursive static IPv6 route might not be added to the IP routing table even if the specified
next hop resolves to a valid IPv6 output interface in the default route. This occurs when the default
route is removed from the IP routing table and then added to the table. The recursive status route
might not be removed from the table and the restored with the default route updates.

might not be removed from the table and the restored with the default route updates.
The workaround is to configure the recursive static IPv6 route with a specific interface.

After the web-based authentication feature with the default settings sends an HTML login page to a
user and authentication succeeds, web-based authentication might not send a Login-Successful
HTML page to the host.

HTML page to the host.
The workaround is to close and open the browser window several times.

When the switch receives more than 1000 IPv6 prefixes from the Border Gateway Protocol (BGP),
the CPU utilization increases.

There is no workaround.

The switch fails when it adds IPv6 routes to the ternary content addressable memory (TCAM).
The workaround is to reload the switch by entering the reload privileged EXEC command.

When a default gateway connects the switch to a TFTP server in a different network segment and
the switch receives messages from the server, an ARP entry for the server is added to the switch ARP
cache. If you replace the default gateway with another one, the switch and replaced default gateway
cannot communicate with the TFTP server until the nonstatic ARP entries time out.

The workaround is to use the clear arp-cache privileged EXEC command to remove all nonstatic
entries from the ARP cache.
