Configuring IP Routing Interfaces

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 681, 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 625.
Using the
Ping Function
Use the IP > General > Ping page to send ICMP echo request packets to another
node on the network.
Parameters
These parameters are displayed:
◆ Host Name/IP Address – IPv4/IPv6 address or alias of the host.
For host name-to-IP address translation to function properly, host name lookup
must be enabled (“Configuring General DNS Service Parameters” on page 643),
and one or more DNS servers specified (see “Configuring a List of Name
Servers” on page 646, or “Configuring Static DNS Host to Address Entries” on
page 647).
◆ Probe Count – Number of packets to send. (Range: 1-16)
◆ Packet Size – Number of bytes in a packet. (Range: 32-512 bytes for IPv4,
0-1500 bytes for IPv6)
The actual packet size will be eight bytes larger than the size specified because
the switch adds header information.
Command Usage
◆ 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,
