Layer 3 ingress and egress traffic. You may specify traffic using standard or extended access-lists. This mechanism
copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port. The source port
is the monitored port (MD) and the destination port is the monitoring port (MG).
deny icmp (for Extended IPv6 ACLs)
Configure a filter to drop all or specific ICMP messages.
NOTE:
Only the options that have been newly introduced in Release 9.3(0.0) and Release 9.4(0.0) are described here. For a
complete description on all of the keywords and variables that are available with this command, refer the topic of this command
discussed earlier in this guide.
