ExtremeWare XOS 11.5 Command Reference Guide
1302
configure vrrp vlan vrid advertisement-interval
configure vrrp vlan <vlan_name> vrid <vridval> advertisement-interval
<interval> [{seconds} | milliseconds]
Description
Configures the time between VRRP advertisements (pings) in seconds or milliseconds.
Syntax Description
Default
The advertisement interval is 1 second.
Usage Guidelines
The advertisement interval specifies the interval between advertisements sent by the master router to
inform the backup routers that its alive. You must use whole integers when configuring the
advertisement interval.
An extremely busy CPU can create a short dual master situation. To avoid this, increase the
advertisement interval.
The seconds range is 1 through 255. The switch uses the seconds interval by default. You do not need to
specify the
seconds
keyword to configure the advertisement interval in seconds.
The milliseconds range is 100 through 999. Since the switch uses the seconds interval by default, you
must specify the
milliseconds
keyword to configure the advertisement interval in milliseconds.
To view your VRRP configuration, including the configured advertisement interval, use one of the
following commands:
●
show vrrp {detail}
●
show vrrp vlan <vlan_name> {stats}
Out of Range Error Messages.
If you enter a number that is out of the seconds or milliseconds range, the
switch displays an error message.
vlan_name
Specifies the name of a VRRP VLAN.
vridval
Specifies a VRRP Virtual Router ID (VRID). Value can be in the range of 1-
255.
interval
Specifies the time interval between advertisements in seconds unless otherwise
specified as milliseconds. The default is 1 second.
The range is 1 through 255 seconds or 100 through 999 milliseconds.
NOTE: If you must configure the range in milliseconds, specify the
milliseconds
keyword. If you enter a number from 100 through 255 and do
not specify the
milliseconds
keyword, the interval defaults to seconds.
