meminfo

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

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.

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
^C

This example shows how to ping IP host elvis 10 times using 1200 byte packets:

Console> ping -s elvis 1200 10
PING elvis:1200 data bytes
1208 bytes from elvis:icmp_seq=0. time=3 ms

1208 bytes from elvis:icmp_seq=5. time=3 ms
1208 bytes from elvis:icmp_seq=6. time=3 ms
1208 bytes from elvis:icmp_seq=7. time=3 ms
1208 bytes from elvis:icmp_seq=8. time=4 ms
1208 bytes from elvis:icmp_seq=9. time=3 ms

reconfirm vmps

Use the reconfirm vmps command to reconfirm the current dynamic port VLAN membership assignments with the VMPS server.

Syntax Description

This command has no arguments or keywords.

Defaults

This command has no default setting.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

VMPS database changes are not conveyed automatically to switches participating in VMPS. Therefore, after making a VMPS database change, use this command on VMPS clients and servers to apply the database changes.

Examples

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)

Related Commands
