Configure Filters, ICMP Packets

To create a filter for ICMP packets with a specified sequence number, use the following commands.

Create either an extended IPv4 or IPv6 ACL and assign it a unique name.
CONFIGURATION mode

ip access-list extended access-list-name

ipv6 access-list extended access-list-name
Configure an extended IP ACL filter for ICMP packets.
CONFIG-EXT-NACL mode

seq sequence-number {deny | permit} icmp {source mask | any | host ip-address} [count [byte]] [order] [monitor [session-id]] [fragments]

The ICMP packets cannot be filtered using mirroring ACL.

The following example shows the configuration to filter ICMP packets using IPv4 ACL:

DellEMC(config-ext-nacl)#show config
!
ip access-list extended icmp
seq 5 permit icmp any any echo count
seq 10 permit icmp any any echo-reply count
seq 15 permit icmp any any host-unreachable count
seq 20 permit icmp any any host-unknown count
seq 25 permit icmp any any network-unknown count
seq 30 permit icmp any any net-unreachable count
