Pinging Fwsm Interfaces - Cisco 7604 Configuration Manual

Testing Your Configuration
You can alternately use logging buffer debug to send messages to a buffer, and then view them later
using the show logging command.
To send the system log messages to your Telnet or SSH session, enter the following command:
Step 3
hostname(config)# terminal monitor
To enable system log messages, enter the following command:
Step 4
hostname(config)# logging enable
The following example shows a successful ping from an external host (209.165.201.2) to the FWSM
outside interface (209.165.201.1):
hostname(config)# debug icmp trace
Inbound ICMP echo reply (len 32 id 1 seq 256) 209.165.201.1 > 209.165.201.2
Outbound ICMP echo request (len 32 id 1 seq 512) 209.165.201.2 > 209.165.201.1
Inbound ICMP echo reply (len 32 id 1 seq 512) 209.165.201.1 > 209.165.201.2
Outbound ICMP echo request (len 32 id 1 seq 768) 209.165.201.2 > 209.165.201.1
Inbound ICMP echo reply (len 32 id 1 seq 768) 209.165.201.1 > 209.165.201.2
Outbound ICMP echo request (len 32 id 1 seq 1024) 209.165.201.2 > 209.165.201.1
Inbound ICMP echo reply (len 32 id 1 seq 1024) 209.165.201.1 > 209.165.201.2
The preceding example shows the ICMP packet length (32 bytes), the ICMP packet identifier (1), and
the ICMP sequence number (the ICMP sequence number starts at 0 and is incremented each time a
request is sent).

Pinging FWSM Interfaces

To test that the FWSM interfaces are up and running and that the FWSM and connected routers are
routing correctly, you can ping the FWSM interfaces.
You can ping only the closest interface. Pinging the far interface is not supported.
Note
To ping the FWSM interfaces, perform the following steps:
Create a sketch of your single mode FWSM or security context showing the interface names, security
Step 1
levels, and IP addresses. The sketch should also include any directly connected routers, and a host on the
other side of the router from which you will ping the FWSM. You will use this information for this
procedure as well as the procedure in the
example:
