Verifying an IP Address

This section explains how to determine the existence of an IP address, and whether it is up and accepting requests.

You can use the ping command with the IPv4 address to send echo messages that indicate whether a given address is available. In addition the ping command returns the following information:

time in milliseconds it took the ICMP packets to reach the destination and return
statistics that indicate the number of packets transmitted, the number of packets received, and the percentage of packet loss.
time in milliseconds for the minimum, average, and maximum RTTs. The default timeout is 64 milliseconds.

The following example shows the ping command used with IPv4 address 10.0.0.1:

ORACLE# ping 172.30.1.150
PING 172.30.1.150: 56 data bytes
64 bytes from 172.30.1.150: icmp_seq=0. time=1. ms
64 bytes from 172.30.1.150: icmp_seq=1. time=0. ms
64 bytes from 172.30.1.150: icmp_seq=2. time=0. ms
64 bytes from 172.30.1.150: icmp_seq=3. time=0. ms
----172.30.1.150 PING Statistics----
4 packets transmitted, 4 packets received, 0% packet loss
round-trip (ms)  min/avg/max = 0/0/1

Note:

The system does not allow you to ping from a secondary SBC media interface, presenting a warning if you try. This prevents you from creating conflicts in the resolution of your interfaces in neighboring switches.

Specifying a Source Address for ICMP Pings

The Oracle Communications Session Border Controller's ping command can also be used to set the source IP address (a valid network interface) to use when sending ICMP pings. You must enter the IP address for the entity you want to ping first, followed by the source IP address.

To specify a source address for an ICMP ping:

At the main system prompt, type ping and a Space, the IP address of the entity you want to ping, the network interface, and then the source IP address you want to use, and then press Enter.
```
ORACLE # ping 124.7.58.6 core:0 172.30.56.6
```
