DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Configures the community string.
snmp-server community string
[view view-name] [ro | rw]
[access-list-number]
Step 2
The @ symbol is used for delimiting the context information. Avoid using
the @ symbol as part of the SNMP community string when configuring
this command.
Note
Example:
Switch(config)# snmp-server
community comaccess ro 4
•
For string, specify a string that acts like a password and permits access to the
SNMP protocol. You can configure one or more community strings of any
length.
•
(Optional) For view-name, specify the view record accessible to the community.
•
(Optional) Specify either read-only (ro) if you want authorized management
stations to retrieve MIB objects, or specify read-write (rw) if you want
authorized management stations to retrieve and modify MIB objects. By
default, the community string permits read-only access to all objects.
•
(Optional) For access-list-number, enter an IP standard access list numbered
from 1 to 99 and 1300 to 1999.
(Optional) If you specified an IP standard access list number in Step 2, then create
the list, repeating the command as many times as necessary.
access-list access-list-number {deny
| permit} source [source-wildcard]
Step 3
Example:
Switch(config)# access-list 4
deny any
•
For access-list-number, enter the access list number specified in Step 2.
•
The deny keyword denies access if the conditions are matched. The permit
keyword permits access if the conditions are matched.
•
For source, enter the IP address of the SNMP managers that are permitted to
use the community string to gain access to the agent.
•
(Optional) For source-wildcard, enter the wildcard bits in dotted decimal
notation to be applied to the source. Place ones in the bit positions that you
want to ignore.
Recall that the access list is always terminated by an implicit deny statement for
everything.
