Command ping, Defaults, User Guidelines, 163 | Dell 28XX specs

•prefix-length —Range:8-30

•default-gatewayip-address—Valid IP address

Defaults

No IP address is defined for interfaces

Command Modes

Interface Configuration VLAN mode.

User Guidelines

•Assigning an IP address to an interface does not disable L2 protocols, such as STP.

•Defining a static IP address on an interface implicitly removes the DHCP client configuration on the interface.

•Interface context may be VLAN 1 only

Examples

switch(config)> interface vlan 1

switch(config-if)> ip address 131.108.1.27 255.255.255.0 default-gateway131.108.1.1

Command: ping

Use the ping command to send ICMP echo request packets to another node on the network.

ping {ip-address hostname} [size packet_size] [count packet_count] [timeout time_out]

Syntax Description

•ip-address— IP address to ping.

•hostname — Hostname to ping.

•packet_size — Number of bytes in a packet. The default is 56 bytes. The actual packet size will be eight bytes larger than the size specified because the switch adds header information.

•packet_count — Number of packets to send, from 1 to 65535 packets. The default is 4 packets. If 0 is entered it pings until stopped.

•time_out — Timeout in milliseconds to wait for each reply, from 50 to 65535 milliseconds. The default is 2000 milliseconds.

Parameters range

•hostname — 1 - 158 characters (Max label size: 63)

•packet_size — IPv4: 56 - 1472
