The following example configures sequence 10 of the MyFilter filter to match packets with 0 as the ICMP code and 24 as the ICMP type:

admin@Switch# set firewall filter MyFilter sequence 10 from protocol icmp code 0
admin@Switch# set firewall filter MyFilter sequence 10 from protocol icmp type 24

The following example removes the match conditions from sequence 10 of the MyFilter filter:

admin@XorPlus# delete firewall filter MyFilter sequence 10 from protocol icmp code
Deleting: 
>   code: 0
OK 
admin@XorPlus# delete firewall filter MyFilter sequence 10 from protocol icmp type
Deleting: 
>   type: 24
OK
