Configuring a rule for IPv6 ICMP types
ServerIron ADX has a set of built-in rules to manage IPv6 icmp types. In this case, the rule
command is used with a <icmp-option> variable specified in Table 16.
The following example configures the "filter4" security filter with a rule to drop packets that
acontain the icmpv6-option type echo-reply.
ServerIronADX(config)# security filter filter4
ServerIronADX(config-sec-filter4)#rule icmp-type echo-reply drop
Syntax: [no] rule ip-option <icmpv6-type> [log | no-log] [drop | no-drop]
The <ipv6-type> variable is specified as one of the options described in Table 16.
The log parameter directs the ServerIron ADX to drop traffic on the bound interface that matches
the rule specified by the configured <icmpv6-type>. The no-log parameter disables this function.
The drop parameter directs the ServerIron ADX to drop traffic on the bound interface that matches
the rule specified by the configured <icmpv6-type>. The no-drop parameter disables this function
