meminfo

Use the meminfo command to display information about the main memory, packet memory, and NVRAM.

meminfo [-l]

Syntax Description

-l	(Optional) Keyword to specify the long listing, which displays the supported DRAM configurations.

Defaults

This command has no default settings.

Command Types

ROM monitor command.

Command Modes

Normal.

Usage Guidelines

The minus sign (-) is required with the -l option.

Examples

This example shows how to use the meminfo command:

rommon 9 > meminfo

Main memory size: 16 MB in 32 bit mode.

Available main memory starts at 0xa000e000, size 16328KB

IO (packet) memory size: 25 percent of main memory.

NVRAM size: 32KB

ping

Use the ping command set to send ICMP echo-request packets to another node on the network. You can also use the ping command without arguments to configure ping.

ping -s host

ping -s host [packet_size] [packet_count]

ping

Syntax Description

-s	Keyword to cause ping to send one datagram per second, printing one line of output for every response received.
host	IP address or IP alias of the host.
packet_size	(Optional) Number of bytes in a packet, from 56 to 1472 bytes.
packet_count	(Optional) Number of packets to send; valid values are from 0 to 2,147,483,647.

Defaults

The defaults for ping -s are:

•packet_size is 56 bytes

•packet_count is 2,147,483,647

The defaults for ping with no arguments are:

•packet_size is 56 bytes

•packet_count is 5

•wait time is 2 seconds

•Target IP address is none (this is a mandatory field)

•Source address is the host IP address

Command Types

Switch command.

Command Modes

Normal or privileged.

Usage Guidelines

General ping command guidelines:

•Press Ctrl-C to stop pinging.

•Continuous ping means that, unless you press Ctrl-C to stop pinging, packets are generated continually and dispatched to the host.

•The actual packet size is 8 bytes larger than the size you specify because the switch adds header information.

•Normal response—The normal response occurs in 1 to 10 seconds, depending on network traffic.

Following are guidelines for the ping -s command:

•The maximum waiting time before timing out is 2 seconds.

•A new ping packet is generated after one second of sending the previous packet, regardless of whether an echo-reply is received or not.

•If you do not enter a packet count, continuous ping results.

•Network or host unreachable—The switch found no corresponding entry in the route table.

•Destination does not respond—If the host does not respond, a "no answer from host" appears in 2 seconds.

•Destination unreachable—The gateway for this destination indicates that the destination is unreachable.

Following are guidelines for the ping command without arguments:

•The ping host command is accepted in normal mode only. The parameters take the default values automatically.

•The target IP address is a mandatory field to be entered.

•The maximum waiting time is configurable.

•A new ping packet is generated only when a echo-reply is received.

•If you enter a packet count of 0, this results in continuous ping.

•Returns output only when a response is received or you press Return.

•Available in privileged mode only.

•When configuring ping, you must either press Return or enter a response. Valid responses and appropriate values are as following:

–Target IP address: IP address or host name of the destination node you plan to ping.

–Number of Packets: Number of ping packets to be sent to the destination address; valid values are from 0 to 2,147,483,647 (0 specifies continuous ping).

–Datagram size: Size of the ping packet; valid values are from 56 to 1472 bytes.

–Timeout in seconds: Timeout interval; valid values are from 0 to 3600 seconds.

–Source IP Address [(default)]: IP address or IP alias of the source.

Examples

This example shows how to ping a host with IP alias elvis a single time:

Console> ping elvis

This command has no arguments or keywords.

Defaults

This command has no default settings.

Command Types

Switch command.
