Unsupported Commands in Cisco IOS Release 12.2(53)EX
This appendix lists some of the command-line interface (CLI) commands that appear when you enter the question mark (?) at the Cisco CGS 2520 switch prompt but are not supported in this release, either because they are not tested or because of switch hardware limitations. This is not a complete list. The unsupported commands are listed by software feature and command mode.
Access Control List Command
Unsupported Global Configuration Commands
access-list rate-limit acl-index { precedence | mask prec-mask }
Unsupported Privileged EXEC Commands
access-enable [ host ] [ timeout minutes ]
access-template [ access-list-number | name ] [ dynamic-name ] [ source ] [ destination ] [ timeout minutes ]
clear access-template [ access-list-number | name ] [ dynamic-name ] [ source ] [ destination ].
ARP Commands
Unsupported Global Configuration Commands
arp ip-address hardware-address smds
Unsupported Interface Configuration Commands
Boot Loader Commands
Unsupported Global Configuration Command
Unsupported User EXEC Command
Debug Commands
Embedded Event Manager Commands
Unsupported Applet Configuration Commands
no event interface name [ interface-name ] parameter [counter-name] entry-val [entry counter value] entry-op {gt | ge | eq | ne |lt | le} [entry-type {increment | rate | value] [ exit-va l [exit value] exit-op {gt | ge | eq | ne |lt | le} exit-type { increment | rate | value}][average-factor <average-factor-value>]
Unsupported Global Configuration Commands
Unsupported Privileged EXEC Commands
event manager update user policy [policy-filename | group [group name expression] ] | repository [url location]
Parameters are not supported for this command:
event manager run [ policy name ] |< paramater1 >|... < paramater15 >|
HSRP Commands
Unsupported Global Configuration Commands
Unsupported Interface Configuration Commands
IEEE 802.1x Commands
Unsupported Interface Configuration Commands

Note The dot1x credentials profile global configuration command is still supported.
Unsupported Privileged EXEC Commands
IGMP Snooping Commands
Unsupported Global Configuration Commands
Interface Commands
Unsupported Global Configuration Commands
Unsupported Interface Configuration Commands
Unsupported Privileged EXEC Commands
show interfaces [ interface-id | vlan vlan-id ] [ crb | fair-queue | irb | mac-accounting | precedence | irb | random-detect | rate-limit | shape ]
IP Multicast Routing Commands
Unsupported Global Configuration Commands
ip multicast-routing vrf vrf-name
ip pim accept-rp { address | auto-rp } [ group-access-list-number ]
Unsupported Interface Configuration Commands
frame-relay ip rtp header-compression [ active | passive ]
frame-relay map ip ip-address dlci [ broadcast ] compress
frame-relay map ip ip-address dlci rtp header-compression [ active | passive ]
ip igmp helper-address ip-address
ip multicast helper-map { group-address | broadcast } { broadcast-address | multicast-address } extended-access-list-number
ip multicast rate-limit { in | out } [ video | whiteboard ] [ group-list access-list ] [ source-list access-list ] kbps
ip multicast ttl-threshold ttl-value (instead, use the ip multicast boundary access-list-number interface configuration command)
Unsupported Privileged EXEC Commands
clear ip rtp header-compression [ type number ]
The debug ip packet command displays packets received by the switch CPU. It does not display packets that are hardware-switched.
The debug ip mcache command affects packets received by the switch CPU. It does not display packets that are hardware-switched.
The debug ip mpacket [ detail ] [ access-list-number [ group-name-or-address ] command affects only packets received by the switch CPU. Because most multicast packets are hardware-switched, use this command only when you know that the route will forward the packet to the CPU.
show frame-relay ip rtp header-compression [ interface type number ]
The show ip mcache command displays entries in the cache for those packets that are sent to the switch CPU. Because most multicast packets are switched in hardware without CPU involvement, you can use this command, but multicast packet information is not displayed.
The show ip mpacket commands are supported but are only useful for packets received at the switch CPU. If the route is hardware-switched, the command has no effect because the CPU does not receive the packet and cannot display it.
IP Unicast Routing Commands
Unsupported BGP Router Configuration Commands
Unsupported Global Configuration Commands
ip accounting-list ip-address wildcard
ip cef accounting [ per-prefix ] [ non-recursive ]
ip cef traffic-statistics [ load-interval seconds ] [ update-rate seconds ]]
Unsupported Interface Configuration Commands
ip load-sharing [ per-packet ]
ip load-sharing [ per-packet ]
Unsupported Privileged EXEC or User EXEC Commands
clear ip accounting [ checkpoint ]
clear ip bgp address flap-statistics
show cef [ drop | not-cef-switched ]
show ip accounting [ checkpoint ] [ output-packets | access-violations ]
show ip bgp regexp regular expression
Unsupported Route Map Commands
match route-type for policy-based routing (PBR)
set as-path { tag | prepend as-path-string }
set dampening half-life reuse suppress max-suppress-time
set default interface interface-id [ interface-id..... ]
set interface interface-id [ interface-id..... ]
set ip default next-hop ip-address [ ip-address..... ]
Unsupported VPN Configuration Commands
MAC Address Commands
Unsupported Global Configuration Commands
Unsupported Privileged EXEC Commands
show mac-address-table address
show mac-address-table aging-time
show mac-address-table dynamic
show mac-address-table interface
show mac-address-table multicaset
show mac-address-table notification
show mac address-table multicast

Note Use the show ip igmp snooping groups privileged EXEC command to display Layer 2 multicast address-table entries for a VLAN.
Miscellaneous Commands
Unsupported Global Configuration Commands
errdisable detect cause dhcp-rate-limit
errdisable recovery cause dhcp-rate-limit
errdisable recovery cause unicast flood
l2protocol-tunnel global drop-threshold
Unsupported Privileged EXEC Commands
Unsupported show platform Commands
Unsupported User EXEC Commands
MSDP Commands
Unsupported Global Configuration Commands
ip msdp default-peer ip-address | name [ prefix-list list ] (Because BGP/MBGP is not supported, use the ip msdp peer command instead of this command.)
Unsupported Privileged EXEC Commands
NetFlow Commands
Unsupported Global Configuration Commands
QoS Commands
Unsupported Global Configuration Command
Unsupported Interface Configuration Command
Unsupported policy-map Class Police Configuration Mode Command
RADIUS Commands
Unsupported Global Configuration Commands
aaa authentication feature default enable
aaa authentication feature default line
authentication command bounce-port ignore
authentication command disable-port ignore
SNMP Commands
Unsupported Global Configuration Commands
Spanning Tree Commands
Unsupported Global Configuration Command
Unsupported Interface Configuration Command
Storm Control Commands

Note Although visible in the command line interface, commands for configuring small-frame thresholds are not needed on the switch because the existing broadcast storm disable feature correctly handles small frames.
