[
match-all
|
match-any
]
class-map-name
Step 2
match-any. The name can be a maximum of 64 characters
long and is case sensitive.
Example:
switch(config)# class-map type control-plane
ClassMapA
switch(config-cmap)#
You cannot use class-default, match-all, or
match-any as class map names.
Note
Specifies matching for an IP ACL.
(Optional)
match access-group name access-list-name
Step 3
Example:
The permit and deny ACL keywords are ignored
in the CoPP matching.
Note
switch(config-cmap)# match access-group name
MyAccessList
Specifies matching for IPv4 or IPv6 ICMP redirect
exception packets.
(Optional)
match exception
{
ip
|
ipv6
}
icmp redirect
Example:
Step 4
switch(config-cmap)# match exception ip icmp
redirect
Specifies matching for IPv4 or IPv6 ICMP unreachable
exception packets.
(Optional)

(ARP) and Reverse Address Resolution Protocol (RARP)
packets.
match protocol arp
Example:
switch(config-cmap)# match protocol arp
Step 7
Exits class map configuration mode.
exit
Example:
Step 8
switch(config-cmap)# exit
switch(config)#
Displays the control plane class map configuration.
(Optional)
show class-map type control-plane
[
class-map-name
]
Step 9
Example:
switch(config)# show class-map type control-plane
Copies the running configuration to the startup
