C HAPTER 18 | General IP Routing
Configuring IP Routing Interfaces
– 745 –
If the switch is configured to advertise itself as the default gateway, a
routing protocol must still be used to determine the next hop router for any
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 753, 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 696.
USING THE
PING FUNCTION
Use the IP > General > Ping page to send ICMP echo request packets to
another node on the network.
CLI REFERENCES
◆ "ping" on page 1654
PARAMETERS
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: 32-1472 bytes for
IPv4, 0-512 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, include zone-id information indicating the VLAN identifier after
