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 setting.

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

ping [-s] host [packet_size] [packet_count]

Syntax Description

-s	(Optional) Argument to cause ping to send one datagram per second when a response is received from the specified host.
host	IP address or IP alias of the host.
packet_size	(Optional) Number of bytes in each ICMP echo request packet.
packet_count	(Optional) Number of packets to send.

Defaults

The default is to send a single 56-byte ICMP echo request packet to the specified host.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

Press Ctrl-C to stop pinging.

Following are sample 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 "no answer from host" appears in ten seconds.

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

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

Examples

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

Console> ping elvis

elvis is alive

Console> 

This example shows how to ping a host with IP alias elvis once per second until you press Ctrl-C to stop pinging:

Console> ping -s elvis

ping elvis: 56 data bytes

64 bytes from elvis: icmp_seq=0. time=11 ms

64 bytes from elvis: icmp_seq=1. time=8 ms

64 bytes from elvis: icmp_seq=2. time=8 ms

64 bytes from elvis: icmp_seq=3. time=7 ms

64 bytes from elvis: icmp_seq=4. time=11 ms

64 bytes from elvis: icmp_seq=5. time=7 ms

64 bytes from elvis: icmp_seq=6. time=7 ms

This example shows how to reconfirm the current dynamic port VLAN membership with VMPS:

Console (enable) reconfirm vmps

reconfirm process started

Use 'show dvlan statistics' to see reconfirm status

Console (enable)
