Note for later – installing ip rules on a brocade SAN switch
After forgetting what I did previously and I eventually managed to lock myself out of the fabric.
So instead of adding a rule to disable telnet, you will prefer to clone the rule set and modify it.
#ipfilter –clone CurrentSec -from default_ipv4
#ipfilter –show (write down the rule number for Telnet 23)
#ipfilter –delrule CurrentSec -rule 2
#ipfilter –addrule CurrentSec -rule 2 -sip any -dp 23 -proto tcp -act deny
#ipfilter –save CurrentSec
#ipfilter –activate CurrentSec
