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]
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.
