Description (partial)

Cannot configure IPv6 address as destination for ERSPAN - see below from customer

switches in clusters that will be ipv6-only. What I see for ERSPAN is:
# conf t
monitor session 4 type erspan-source
destination ip 2401:db00:2111:f003:face:0:39:0
% Invalid ip address at
destination ?
ip Configure remote IP address

Its not supported because ASIC cannot do it.
This needs to be documented.
