Displaying GSLB information | 1 |
This example shows the RTT prefix cache entry that contains site IP address 192.1678.2.1. The prefix source line indicates that the prefix cache entry that matches the site address was added statically. Notice that a prefix cache entry can have more than one source. In this case, the prefix was statically configured but a specific entry (listed below under the domain name “www.brocade.com”) was created when the GSLB ServerIron ADX received RTT information from the site ServerIron ADX for a site address within the prefix.
In the following example, a statically generated entry that the GSLB ServerIron ADX created is displayed. The statically generated entries have an
ServerIronADX(config)# show gslb cache 61.1.1.1
prefix length = 8, prefix = 60.0.0.0, region = ASIA prefix source = geographic
This display shows the following information.

prefix length |
| Specifies the length of the address prefix. The GSLB ServerIron ADX | |
|
| initially generates the prefix tree using the IANA (geographic) allocated | |
|
| address prefixes, which have variable lengths. Dynamically generated | |
|
| cache entries (generated by client queries) have a fixed prefix length, as | |
|
| defined by the RTT | |
|
|
| |
prefix |
| Specifies the prefix. All client addresses beginning with this prefix are | |
|
| aggregated in a single RTT entry. | |
|
|
| |
region |
| Specifies the geographic location of this client prefix. This field can have | |
|
| one of the following values: | |
|
| • | ASIA |
|
| • | EUROPE |
|
| • | |
|
| • | |
|
|
| |
prefix source |
| Specifies the prefix source. This field can have one of the following | |
|
| values: | |
|
| • geographic: displayed for static entries (entries generated by the | |
|
|
| GSLB ServerIron ADX itself when initializing the RTT cache) |
|
| • client query: displayed for entries generated by client queries | |
|
| • static: displayed for static entries entered by you (refer to “Adding | |
|
|
| static prefix cache entries” on page 55) |
|
| NOTE: If a static entry is long enough (greater than 20 bits) and has | |
|
|
| been accessed by a client query, the entry can show both |
|
|
| sources. |
|
| Notice that a prefix cache entry can have more than one source. | |
|
|
| |
site |
| Specifies the name of the site. | |
|
| ||
ServerIron ADX | Specifies the name and IP address of the ServerIron ADX. | ||
|
|
| |
rtt |
| Specifies the RTT value. | |
