icmp
config>router>interface
Supported on all 7210 SAS platforms as described in this document
Commands in this context configure Internet Control Message Protocol (ICMP) parameters on a network IP interface. ICMP is a message control and error reporting protocol that also provides information relevant to IP packet processing.
[no] mask-reply
config>router>if>icmp
Supported on all 7210 SAS platforms as described in this document
This command enables responses to ICMP mask requests on the router interface.
If a local node sends an ICMP mask request to the router interface, the mask-reply command configures the router interface to reply to the request.
The no form of this command disables replies to ICMP mask requests on the router interface.
mask-reply
redirects [number seconds]
no redirects
config>router>if>icmp
Supported on all 7210 SAS platforms as described in this document
This command enables and configures the rate for ICMP redirect messages issued on the router interface.
When routes are not optimal on this router, and another router on the same subnetwork has a better route, the router can issue an ICMP redirect to alert the sending node that a better route is available.
The redirects command enables the generation of ICMP redirects on the router interface. The rate at which ICMP redirects are issued can be controlled with the optional number and time parameters by indicating the maximum number of redirect messages that can be issued on the interface for a specific time interval.
The no form of this command disables the generation of ICMP redirects on the router interface.
Specifies the maximum number of ICMP redirect messages to send, expressed as a decimal integer. This parameter must be specified with the time parameter.
Specifies the time frame, in seconds, used to limit the number of ICMP redirect messages that can be issued
ttl-expired [number seconds]
no ttl-expired
config>router>if>icmp
Supported on all 7210 SAS platforms as described in this document
This command configures the rate that Internet Control Message Protocol (ICMP) Time To Live (TTL) expired messages are issued by the IP interface.
The no form of this command disables the generation of TTL expired messages.
Specifies the maximum number of ICMP TTL expired messages to send, expressed as a decimal integer. The seconds parameter must also be specified.
Specifies the time frame, in seconds, used to limit the number of ICMP TTL expired messages that can be issued, expressed as a decimal integer.
unreachables [number seconds]
no unreachables
config>router>if>icmp
Supported on all 7210 SAS platforms as described in this document
This command enables and configures the rate for ICMP host and network destination unreachable messages issued on the router interface.
The unreachables command enables the generation of ICMP destination unreachables on the router interface. The rate at which ICMP unreachables is issued can be controlled with the optional number and seconds parameters by indicating the maximum number of destination unreachable messages that can be issued on the interface for a specific time interval.
The no form of this command disables the generation of ICMP destination unreachables on the router interface.
Specifies the maximum number of ICMP unreachable messages to send, expressed as a decimal integer. The seconds parameter must also be specified.
Specifies the time frame, in seconds, used to limit the number of ICMP unreachable messages that can be issued, expressed as a decimal integer.
