Nonstop forwarding allows the forwarding plane of stack units to continue to
forward packets while the control and management planes restart as a result
of a power failure, hardware failure, or software fault on the stack
management unit.
Example
console(config)#nsf
ping
Use the ping command to check the accessibility of the specified station on
the network.
Use of the optional VRF parameter executes the command within the
context of the VRF specific routing table.
Syntax
ping [vrf vrf-name] {[ ip ]ip-address | hostname | { ipv6 { interface
interface-id | vlan vlan-id | loopback loopback-id | out-of-band | tunnel
tunnel-id} link-local-address | ipv6-address | hostname} [count count] [
interval interval] [ size size] [source { ip-address | ipv6-address | interface-id
| vlan vlan-id | out-of-band}]
• ip-address—The IPv4 address to ping.
• ipv6-address—The IPv6 address to ping.
• link-local-address — The link local IPv6 address to ping.
• hostname—The domain name of the host to ping. (Range: 1–158
characters). When used with the IPv6 keyword, the hostname will be
resolved to an IPv6 address, otherwise, it will be resolved to an IPv4
address.
• vrf-name—(Optional) The name of the VRF instance from which to
ping. Only hosts reachable from within the VRF instance can be pinged.
If a source parameter is specified in conjunction with a VRF parameter,
it must be a member of the VRF. The ipv6 parameter cannot be used
with the vrf parameter.
• interface-id—The interface over which a link local IPv6 address may be
reached. Only available when used with the IPv6 keyword.
