user-definable. To set up a trap host means to create a trap
manager by assigning an IP address to host the trap message.
In other words, the trap host is a network management unit
with SNMP manager receiving the trap message from the
managed switch with SNMP agent issuing the trap message.
6 trap hosts can prevent the important trap message from
losing.
For each public trap, the switch supports the trap event Cold
Start, Warm Start, Link Down, Link Up and Authentication
Failure Trap. They can be enabled or disabled individually.
When enabled, the corresponded trap will actively send a
trap message to the trap host when a trap happens. If all
public traps are disabled, no public trap message will be sent.
As to the Enterprise (no. 6) trap is classified as private trap,
which are listed in the Trap Alarm Configuration function
folder.

The 24 Gigabit L2 Managed Switch access control list (ACL) is probably the most
commonly used object in the IOS. It is used for packet filtering but also for selecting types
of traffic to be analyzed, forwarded, or influenced in some way.
The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters
etc. Here we will just go over the standard and extended access lists for TCP/IP. As you
create ACEs for ingress classification, you can assign a policy for each port, the policy
number is 1-8, however, each policy can be applied to any port. This makes it very easy to
determine what type of ACL policy you will be working with.
