Displaying RTT information

The GSLB ServerIron ADX maintains a cache of RTT information received from the site ServerIron
ADXs through the GSLB protocol. You can display the RTT information the GSLB ServerIron ADX has
related to a client IP address. To display the RTT information, specify a potential client address, as
shown in the following example.
ServerIronADX(config)# show gslb cache 209.157.0.0
prefix length = 20, prefix = 209.157.0.0, region = N-AM
prefix source =

brocade.com:
site = sunnyvale,
site = atlanta,
The command in this example shows the RTT prefix information the GSLB ServerIron ADX has
related to client IP address 209.156.100.100. In this case, the GSLB ServerIron ADX has two RTT
entries for zone www.brocade.com.
Syntax: show gslb cache <ip-addr>
The <ip-addr> command specifies a site address.
The following example shows information for a user-configured static entry.
ServerIronADX(config)# show gslb cache 192.168.2.1
prefix length = 24, prefix = 192.168.2.0, region = N-AM
prefix source = static, client-query
