Displaying GSLB information
1
The show server dynamic sessions command provides a simple way to list the real servers. The
output is based on the output for the show server sessions command. However, in the case of
dynamically created servers, there are no meaningful session statistics in this display.
Specifying the source IP of probes
In previous GSLB implementations, both the ICMP and DNS RTT probes sent out for the active RTT
gathering feature used the IP address of the outgoing interface to the LDNS server as the source IP.
Starting in 09.2.00, you can specify the IP address to be used as the source IP of these probes, by
using the following command.
Syntax: gslb src-ip-active-rtt <ip-address>
The <ip-address> is an IP address already configured on a ServerIron ADX interface.
If you specify an IP address not configured on the device, the previous CLI command will reject it.
Additionally if you remove the IP address on an interface (and this is the IP configured for active
RTT probing), then the ServerIron ADX will remove this IP as the GSLB source IP for active RTT
gathering.
Displaying information in the prefix cache
The GSLB ServerIron ADX's prefix cache stores information received from site ServerIron ADXs
through the GSLB protocol. You can display information in the prefix cache using the show gslb
cache command.
To display all entries in the GSLB ServerIron ADX's prefix cache, enter the following command.
ServerIronADX# show gslb cache all

prefix length = 8, prefix = 3.0.0.0, region = N-AM

prefix source = geographic (static),


prefix length = 8, prefix = 4.0.0.0, region = N-AM

prefix source = geographic (static),


prefix length = 8, prefix = 6.0.0.0, region = N-AM

prefix source = geographic (static),

...
Syntax: show gslb cache all
To display all the static entries in the GSLB ServerIron ADX's prefix cache, enter the following
command.
ServerIronADX# show gslb cache all static

prefix length = 24, prefix = 192.168.20.0, region = N-AM

prefix source = static,


prefix length = 29, prefix = 192.168.20.248, region = N-AM

prefix source = static,

...
Syntax: show gslb cache all static
To display the affinity entries configured for client prefixes on the GSLB ServerIron ADX, enter the
following command.
