Command Default
Matching based on ICMP type is not configured.
Parameters
- eq
icmp-type-1
- Specifies that
matching occurs when the packet ICMP type is equal to the specified ICMP
type or well-known ICMP type value.
- gt
icmp-type-1
- Specifies that
matching occurs when the packet ICMP type is greater than the specified ICMP
type or well-known ICMP type value.
- lt
icmp-type-1
- Specifies that
matching occurs when the packet ICMP code is less than the specified ICMP
type or well-known ICMP type value.
- neq
icmp-type-1
[ … icmp-type-32
]
- Specifies that
matching occurs when the packet ICMP type (or ICMP type value) is not equal
to all of the specified ICMP types. You can specify a maximum of 32 ICMP types.
S
- range
icmp-type-1
icmp-type-2
- Specifies that
matching occurs when the packet ICMP type is within the range of specified
ICMP types or well-known ICMP type values.
Modes
Route-map configuration mode
Usage Guidelines
When match protocol and
match ip icmp-type are
specified in the same stanza, the protocol specified by the match protocol command
must be ICMP; specifying any other protocol value using the match protocol command
results in the rule being evaluated as false and it becomes inactive.
Up to 128
match ip icmp-type
statements are
allowed per
route-map sequence number for the following options:
When multiple match ip
icmp-type statements of the same type exist, matching occurs when
traffic matches any one of the statements.
Only one
match ip icmp-type
statement is
allowed per
route-map sequence number for the following options:
Note
Configuring the
range option may create a lot of TCAM
entries (due to rule expansion).
The no form of the command disables the configuration.
Examples
The
following example shows how to configure matching when the packet ICMP type is
not equal to 5.
device# configure terminal
device(config)# route-map rm permit 4
device(config-route-map-rm/permit/4)# match ip icmp-type neq 5
