Limiting TFTP Servers Used Through SNMP

Beginning in privileged EXEC mode, follow these steps to limit the TFTP servers used for saving and
loading configuration files through SNMP to the servers specified in an access list:
Command
Step 1 configure terminal
Step 2
snmp-server tftp-server-list
access-list-number
Step 3
access-list access-list-number {deny |
permit} source [source-wildcard]
78-11194-03
Purpose
Enter global configuration mode.
Set the system contact string.
For example:
snmp-server contact Dial System Operator at beeper 21555.
Set the system location string.
For example:
snmp-server location Building 3/Room 222
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Limit TFTP servers used for configuration file copies through
SNMP to the servers in the access list.
For access-list-number, enter an IP standard access list numbered
from 1 to 99 and 1300 to 1999.
Create a standard access 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 TFTP servers that can
access the switch.
• (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.
