Fabric OS 5.3.0 administrator guide 139
For an IP Filter policy rule, users can only select port numbers in either the well known or the registered port
number range, between 0 and 49151, inclusive. This means that customers have the ability to control how
to expose the management services hosted on a switch, but not the ability to affect the management traffic
that is initiated from a switch. A valid port number range is represented by a dash, for example 7-30.
Alternatively, service names can also be used instead of port number. Table 36 lists the supported service
names and their corresponding port number.
TCP and UDP protocols are valid selections. Fabric OS 5.3.0 does not support configuration to filter other
protocols. Implicitly, ICMP type 0 and type 8 packets are always allowed to support ICMP echo
request/reply on commands like ping and traceroute. For the action, only “permit” and “deny” are valid.
For every IP Filter policy, the following two rules are always assumed to be appended implicitly to the end
of the policy, see Table 37 . This is to ensure TCP and UDP traffics to dynamic port ranges is allowed, that
way management IP traffic initiated from a switch, such as syslog, radius and ftp, will not be affected.
A switch with Fabric OS 5.3.0 or later will have a default IP Filter policy for IPv4 and IPv6. The default IP
Filter policy cannot be deleted or changed. When an alterative IP Filter policy is activated, the default IP
Filter policy becomes deactivated. Table 38 lists the rules of the default IP Filter policy.
