IP Switching Commands
show mls cef ipv6
ISW-229
Cisco IOS IP Switching Command Reference
May 2008
You can enter this command on the supervisor engine and Multilayer Switching (MLS)-hardware
Layer
3-switching module consoles only. Enter the remote login command to enter a session into the
supervisor engine and distributed forwarding card (DFC)-equipped module to enter the commands.
When entering the ip-address/mask argument, use this format, X:X:X:X::X/mask, where valid values for
mask are from 0 to 128.
Up to 64 IPv6 prefixes are supported.
Yo u m u s t e n t e r th e L4-src-port and L4-dst-port arguments when the load-sharing mode is set to full, for
example, when Layer 4 ports are included in the load-sharing hashing algorithm.
Examples This example shows how to display the hardware IPv6-switching table entries:

This example shows how to display the IPv6 entries for a specific IPv6 address and mask:
Router# show mls cef ipv6 2001:4747::/64
Codes:R - Recirculation, I-IP encap
M-MPLS encap, + - Push label
Index Prefix Out i/f Out Label
160 2001:4747::/64 punt
This example shows how to display all the IPv6-FIB entries that have per-prefix statistics available:
Router# show mls cef ipv6 accounting per-prefix
(I) BEEF:2::/64: 0 packets, 0 bytes
A - Active, I - Inactive
This example shows how to display detailed hardware information:
Router# show mls cef ipv6 detail
Codes: M - mask entry, V - value entry, A - adjacency index, P - FIB Priority
D - FIB Don't short-cut, m - mod-num
Format: IPv6_DA - (C | xtag vpn uvo prefix)
M(128 ): F | 1 FF 1 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF
