TABLE 49 CLI display of global IP configuration information
This field... Displays...
Global settings
ttl The Time-To-Live (TTL) for IP packets. The TTL specifies the maximum
number of router hops a packet can travel before reaching the device. If the
packet’s TTL value is higher than the value specified in this field, the
Brocade router drops the packet.
To change the maximum TTL, refer to “Changing the TTL threshold” on
page 186.
arp-age The ARP aging period. This parameter specifies how many minutes an
inactive ARP entry remains in the ARP cache before the router ages out the
entry.
To change the ARP aging period, refer to
“Changing the ARP aging period” on
page 182.
bootp-relay-max-hops The maximum number of hops away a BootP server can be located from the
Brocade router and still be used by the router’s clients for network booting.
To change this value, refer to “Changing the maximum number of hops to a
BootP relay server” on page 212.
router-id The 32-bit number that uniquely identifies the Brocade router.
By default, the router ID is the numerically lowest IP interface configured on
the router. To change the router ID, refer to
“Changing the router ID” on
page 174.

Subnet Mask The network mask for the IP address.
Next Hop Router The IP address of the router interface to which the Brocade router sends
packets for the route.
Metric The cost of the route. Usually, the metric represents the number of hops to
the destination.
Distance The administrative distance of the route. The default administrative distance
for static IP routes in
Brocade routers is 1.
To list the default administrative distances for all types of routes or to
change the administrative distance of a static route, refer to
“Changing
administrative distances” on page 765.
Policies
Index The policy number. This is the number you assigned the policy when you
configured it.
Action The action the router takes if a packet matches the comparison values in
the policy. The action can be one of the following:
•
deny – The router drops packets that match this policy.
•
permit – The router forwards packets that match this policy.
Source The source IP address the policy matches.
