IP Interface Commands

Command Usage
• Ping sends an echo request to the specified address, and waits for a reply.
Ping output can help determine path reliability, path delays, and if the host is
reachable or functioning.
• If the system cannot map an address for a host name, it returns the message
“Can not get address information for host,” or “protocol not running.”
• To terminate a ping session, type the escape sequence Ctrl-X.
• Using a timeout of zero seconds generates a flood ping, resulting in replies
that are received only from immediately adjacent routers (depending on the
utilization on the both the target and intermediate devices), the distance to the
remote device, and other factors.
• Not all protocols require hosts to support pings. For some protocols, only
another switch or router of the same type may respond to ping requests.
• Use the IPv4
ping
command (page 41-6) for addresses that resolve to IPv4.

the
no
form to remove a static entry from the cache.
Syntax
ipv6 neighbor
ipv6-address
vlan
vlan-id hardware-address
no ipv6 mtu
•
ipv6-address
- The IPv6 address of a neighbor device that can be reached
through one of the network interfaces configured on this router. You can
specify either a link-local or global unicast address formatted according to
RFC 2373 “IPv6 Addressing Architecture,” using 8 colon-separated 16-bit
hexadecimal values. One double colon may be used in the address to
indicate the appropriate number of zeros required to fill the undefined fields.
•
vlan-id
- VLAN ID (Range: 1-4093)
•
hardware-address
- The 48-bit MAC layer address for the neighbor device.
This address must be formatted as six hexadecimal pairs separated by
hyphens.
