Information
On the S4810 and S4820T, First-Hop information is not shown for installed routes in the IPv6
Content Addressable Memory (CAM). However, the same is shown in the Forwarding
Information Base (FIB).
Note: If a route has a mask greater than 64, no output will be displayed, no output will
be displayed for “show ipv6 cam stack-unit unit-number port-set {0-1} ipv6-address”
but an equivalent /64 entry would be listed in the “show ipv6 cam stack-unit
unit-number port-set {0-1}” output. Similarly, if there is more than one ECMP object
with a destination route that has a mask greater than 64, if the first 64 bits in the
destination routes of the ECMP objects are the same, only one route is installed in
CAM even though multiple ECMP path entries exist.
Note: On the S4810 and S4820T, the self address will be displayed in the neighbor
portion for the “show ipv6 cam stack-unit unit-number port-set” command.
