To remove a specific entry in the ARP cache, enter this command:
■ Enhancement (PR_1000438015) — The banner message of the day (MOTD) size has been
increased to support up to 3070 characters.
The size of the login banner page increased from 320 to 3070 characters. The default banner
displays product registration information; the copyright splash is no longer displayed.
If a banner is configured, the banner page is displayed when the user accesses the Web user
interface. The default product registration information is not displayed as there is already a
product registration prompt displayed in the Web user interface.

Classifier-Based Rate Limiting
Classifier-Based Rate Limiting (also known as Rate-Limit Port ACLs or RL-PACLs) allows you to
create an ACL and apply it on a per-port basis to rate-limit network traffic. When packets entering
the port match a PERMIT statement in the ACL, they are rate-limited at the rate you have configured.
If the packet matches a DENY statement, it is not rate-limited. There is an implicit DENY ALL at the
end of the ACL, which means packets with no match are not rate-limited.
Syntax: [no] arp IP-ADDRESS
Allows removal of any dynamic entry in the ARP cache.
