Use the meminfo command to display information about the main memory, packet memory, and NVRAM. With the -l option, the supported DRAM configurations are displayed.
meminfo [-l]
-l | (Optional) Keyword to specify long listing---displays DRAM configurations. |
This command has no default setting.
ROM monitor command.
Normal.
The minus sign (-) is required with the -l option.
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
On a Cisco 3640 router, meminfo -l displays the following tables. The size of the SIMM indicated is its total size. The "-DUAL" attached to the size indicates that the SIMM is a dual-bank SIMM. For example, "8M" indicates that the SIMM is a single bank with a total size of 8 MB. "8M-DUAL" indicates that the SIMM is dual bank with a total size of 8 MB (4 MB on each bank).

Use the ping command to send ICMP echo request packets to another node on the network.
ping [-s] host [packet_size] [packet_count]
-s | (Optional) Keyword to cause ping to send one datagram per second, printing one line of output for every response received. The ping command returns output only when a response is received. |
host | IP address or IP alias of the host. |
packet_size | (Optional) Number of bytes in a packet, from 56 to 1472 bytes. The default is 56 bytes; the actual packet size will be 8 bytes larger than the size specified because the switch adds header information. |
packet_count | (Optional) Number of packets to send. |
This command has no default setting.
Switch command.
Normal.
Press Ctrl-C to stop pinging.
Following are sample results of the ping command:
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 ----elvis PING Statistics---- 7 packets transmitted, 7 packets received, 0% packet loss round-trip (ms) min/avg/max = 7/8/11 Console>

Use the pwd command to show the current setting of the cd command.
pwd [[m/]device:]
m/ | (Optional) Module number of the supervisor engine containing the Flash device. |
device: | (Optional) Device where the Flash resides. |
If no module number or device is specified, pwd defaults to the first module of the active device.
Switch command.
Privileged.
A colon (:) is required after the specified device.
This example shows how to use the pwd command to display the current listing of the cd command:
Console> cd slot0: Default flash device set to slot0. Console> pwd slot0
Use the quit command to exit a CLI session.
quitThis command has no arguments or keywords.
This command has no default setting.
Switch command.
Normal.
The exit and logout commands perform the same function as the quit command.
This example shows how to quit a CLI session:
Console> quit Connection closed by foreign host. host%
Use the repeat command to repeat a command.
repeat [num | string]
number | (Optional) Number of the command. |
string | (Optional) Command string. |
If no argument is specified, the last command is repeated.
ROM monitor command.
Normal.
The optional command number (from the history buffer list) or match string specifies which command to repeat.
In the match string, the most recent command to begin with the specified string is executed again.
If the string contains white space, you must use quotation marks.
This command is usually aliased to the letter "r."
These examples show how to use the repeat command. You use the history command to display the list of previously entered commands:
