own community name. Say, the community name for GET only works for GET
function and can’t be applied to other function such as SET and Trap.

Default Set function: Enable
Default trap host IP address: 0.0.0.0

Trap:
In the switch, there are 6 trap hosts supported. Each of them has its own
community name and IP address; is 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.
Default for all public traps: Enable.
4.9 ACL
The SNMP-24MGB 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.
