Brocade Communications Systems 12.4.00 manual Displaying DNS zone and hosts

Displaying GSLB for IPv6 configurations 2

•Local (weight: 50; ServerIron ADX: 2001:db8::1; VIPs: 2001:db8::180 (HTTP), 2001:db8::181 (HTTP), 2001:db8::121 (FTP)

•TWO (weight: 50; ServerIron ADX: 2001:db8::2; VIPs: 2001:db8::182 (HTTP), 2001:db8::122 (FTP))

•THREE (weight: 0; ServerIron ADX: 2001:db8::3; VIPs: 2001:db8::183 (HTTP), 2001:db8::123 (FTP))

The IP resolution for the domain names is as follows:

•a.b.c.: 2001:db8::180; 2001:db8::181; 2001:db8::182

•b.b.c.: 2001:db8::121; 2001:db8::1.122

After making 36 requests for domain "a.b.c.", the distribution was:

•Site Local got 18 requests (VIP 2001:db8::180 received 9 and VIP 2001:db8::181 received 9)

•Site TWO got 18 requests (VIP 2001:db8::182 received all 18)

Site THREE did not receive any requests because its weight is zero.

Syntax: show gslb traffic site

Displaying DNS zone and hosts

Use the show gslb dns command to view information about the DNS zones and host names on GSLB controllers. The command can be used with or without the <zone-name> variable, which specifies a single zone. If this variable is omitted, all zones are displayed.

NOTE

If you also want to display information about the site and ServerIron ADX on which a VIP is configured, use the show gslb dns detail command instead. Refer to “Displaying detailed DNS information” on page 241.

To display GSLB information about a specific DNS zone, you must specify the zone such as in the example:

ServerIronADX(config)# show gslb dns zone brocade.com

ZONE: brocade.com
HOST: www:
(Global GSLB policy)
GSLB affinity group: global					Flashback		DNS resp.
					delay		selection
					(x100us)		counters
* 10.18.2.155:	cfg	v-ip	ACTIVE N-AM.		TCP	APP	Count(%)
					0	0	1	(33%)
* 10.18.2.166:	cfg	v-ip	ACTIVE N-AM.		0	0	1	(33%)
* 2001:db8::1:	cfg	v-ip	ACTIVE	N-AM.	0	0	1	(33%)
* 2001:db8::5:	cfg	real-ip	DOWN	N-AM.	--	--	0	(0%)

The information displayed is the same as that when you do not specify a zone name, except the zone field is unneeded and thus does not appear.

Syntax: show gslb dns zone [<zone-name>]

The <zone-name>parameter specifies the name of the zone to be displayed.
