This display shows the following information.
Table 16.8: CLI Display of Global IP Configuration Information – Layer 3 Switch
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 Foundry router. If the packet’s TTL value is higher than the value
specified in this field, the Foundry router drops the packet.
To change the maximum TTL, see “Changing the TTL Threshold” on
page 16-29.
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, see “Changing the ARP Aging
Period” on page 16-27.
bootp-relay-max-hops The maximum number of hops away a BootP server can be located
from the Foundry router and still be used by the router’s clients for
network booting.
To change this value, see “Changing the Maximum Number of Hops to
a BootP Relay Server” on page 16-50.
router-id The 32-bit number that uniquely identifies the Foundry router.
By default, the router ID is the numerically lowest IP interface
configured on the router. To change the router ID, see “Changing the
Router ID” on page 16-23.
enabled The IP-related protocols that are enabled on the router.
disabled The IP-related protocols that are disabled on the router.
Static routes
Index The row number of this entry in the IP route table.
IP Address The IP address of the route’s destination.
Subnet Mask The network mask for the IP address.
Next Hop Router The IP address of the router interface to which the Foundry 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 Foundry routers is 1.
To list the default administrative distances for all types of routes or to
change the administrative distance of a static route, see “Changing
Administrative Distances” on page 21-29.
