Description (partial)

ASA 602101 syslog message is applicable for both the IPv4 and IPv6.
However, the explanation of 602101 message seems to be specific to v4, since DF bit is specific to v4.
The explanation should be modified to be applicable for v6 as well.

Error Message %ASA-6-602101: PMTU-D packet number bytes greater than effective mtu number dest_addr= dest_address , src_addr= source_address , prot= protocol

Explanation The ASA sent an ICMP destination unreachable message and fragmentation is needed, but the don't-fragment bit has been set.
