dynamic
[

[
vlan <vlan-id>
]
Argument Description
dynamic
The device forces the multicast server to send all configured multicast-group
data to the source port, without waiting for join requests from receiver ports.
When a user on a receiver port sends a join to a multicast group, it
immediately starts receiving the multicast data.
The response to joins and channel zapping is quick, at the expense of loading
the device with traffic from all the configured multicast groups all the time.
If no multicast group is defined the default will be 224.0.0.1.
Under normal conditions, dynamic mode is preferable.
static
Multicast data is sent only after a request has been sent from a receiver port to
join that multicast group. The response in this mode is slower than the
response in dynamic mode, but the device is not loaded with traffic from
unused multicast groups.
vlan <vlan-
id>
(Optional). ID of the VLAN on which MVR multicast data is expected in the
range <1-4094>.
A.B.C.D
(Optional). The IP multicast address of the MVR group.
count
(Optional). Configure multiple contiguous MVR group addresses. The default
is 1. The allowed range is <1-256>.
querytime
<value>
(Optional). The response time in seconds. The default is 10 seconds. The
allowed range is <1-25> seconds.
Setting the MVR VLAN
The
mvr vlan
command, in Global Configuration mode, specifies the VLAN ID on which
multicast data is received. All the source and receiver ports must belong to this VLAN.
By default, the multicast VLAN ID for MVR is 1.
Command Syntax
device-name
(config)#
mvr
vlan
<vlan-id>
Argument Description
vlan-id
ID of the VLAN on which MVR multicast data is expected. The range is <1-
4094>.
Setting the MVR IP Multicast Group
The
mvr group
command, in Global Configuration mode, statically sets up all the IP multicast
addresses that will take part in MVR. The count parameter is used to configure a contiguous series
of IP addresses. The
no
form of the command, with an IP address specified, removes the specified
