Telnet protocol
6
ATTENTION
The rule number assigned must precede the default rule number for this protocol. For
example, in the defined policy, the Telnet rule number is 2. Therefore, to effectively block
Telnet, the rule number to assign must be 1.
If you choose not to use 1, you must delete the Telnet rule number 2 after adding this rule.
Refer to “Deleting a rule from an IP Filter policy” on page 223 for more information on deleting
IP filter rules.
6. Save the new IP filter policy by typing the ipfilter
--save command.
7. Verify the new policy is correct by typing the ipFilter
--show command.
8. Activate the new IP filter policy by typing the ipfilter
--activate command.
switch:admin> ipfilter --activate BlockTelnet
9. Verify the new policy is active (the default_ipv4 policy should be displayed as defined).
