Configuring IP Routing Interfaces

– 625 –

unknown destinations, i.e., packets that do not match any routing table

entry. If another router is designated as the default gateway, then the

switch will pass packets to this router for any unknown hosts or subnets.

To configure a default gateway for IPv4, use the static routing table as

described on

page 633

, enter 0.0.0.0 for the IP address and subnet mask,

and then specify this switch itself or another router as the gateway. To

configure a gateway for IPv6, see

"Configuring the IPv6 Default Gateway"

on page 579

.

These parameters are displayed:

Host Name/IP Address – IPv4/IPv6 address or alias of the host.

Probe Count – Number of packets to send. (Range: 1-16)

Packet Size – Number of bytes in a packet. (Range: 32-512 bytes,

Default: 32 bytes)
The actual packet size will be eight bytes larger than the size specified

because the switch adds header information.

Use the ping command to see if another site on the network can be

reached.

The following are some results of the ping command:

Normal response - The normal response occurs in one to ten

seconds, depending on network traffic.

Destination does not respond - If the host does not respond, a

“timeout” appears in ten seconds.

Destination unreachable - The gateway for this destination indicates

that the destination is unreachable.

Network or host unreachable - The gateway found no corresponding

entry in the route table.

The same link-local address may be used by different interfaces/nodes

in different zones (RFC 4007). Therefore, when specifying a link-local

address, include zone-id information indicating the VLAN identifier after

the % delimiter. For example, FE80::7272%1 identifies VLAN 1 as the

interface.
