Chapter 29 Configuring SNMP
Configuring SNMP
Beginning in privileged EXEC mode, follow these steps to configure a community string on the switch:
Note
To disable access for an SNMP community, set the community string for that community to the null
string (do not enter a value for the community string).
To remove a specific community string, use the
no snmp-server community
string
global configuration
command.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
snmp-server community
string
[
view
view-name
]
[
ro
|
rw
] [
access-list-name or
number
]
Configure the community string.
Note
The @ symbol is used for delimiting the context information.
Avoid using the @ symbol as part of the SNMP community
string when configuring this command.
•
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
, 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.
Step 3
access-list
access-list-number
{
deny
|
permit
}
source
[
source-wildcard
]
(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.
•
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.
Step 4
end
Return to privileged EXEC mode.
Step 5
show running-config
Verify your entries.
Step 6
copy running-config startup-config
(Optional) Save your entries in the configuration file.
