It seems that a SNMP walk on a IPv6 enabled switch does not show IPV6-MIB related information.
What software ver supports IPV6-MIB?
The cisco Object navigator does not show any images as well :
C:\>snmpwalk -v 2c -c public 10.78.136.100 220.127.116.11.2.1.55
SNMPv2-SMI::mib-2.55 = No Such Object available on this agent at this OID
What is the reason? Does any cisco IOS has ipv6Mib?
