2 129.255.33.68 port 0/15
Execute the show run command on the router to view the
encapsulated VLAN of the interface connected to the route
port, as follows:
interface fastethernet0.1
ip address 1.1.1.1 255.0.0.0
encapsulation dot1q 3
ip pim sparse-mode
exit
The two VLANs need to be configured consistently. Otherwise,
the service packets cannot be received.
Other possible reasons
Refer to fault 1.
Fault 4: The multicast data flow cannot be received after configuring the
static multicast.
Possible Reasons
Judging Methods and Solutions
The configured static
multicast address is wrong.
When the static multicast is configured, use the show l2-
multicast mac-entry static command to view whether the
group address and VLAN attributes are correct, as follows:
switch# show l2-multicast mac-entry static
Current L2 Static Multicast 2 entries
---- -------- ------------------ ----------------------------------
NO. VID Group MAC address Port Number
---- -------- ------------------ ----------------------------------
1 1 0100.5E00.0101
2 1 0100.5E00.0102 [M] port 0/20
The static multicast indicates that port 0/20 can receive the
multicast packets, such as 224.0.1.2, 224.128.1.2 and
225.0.1.2.
The receiver is connected to
the forbidden port of the
static multicast group.
Use the show l2-multicast mac-entry static command to
view the member ports and forbidden ports of the static
multicast group.
switch#show l2-multicast mac-entry static
Current L2 Static Multicast 1 entry
----------------------------------------------------------------
NO. VID Group MAC address Port Number
------------------ ---------------------------------------------
1 100 0100.5E01.0101 [M] port 0/0/40
[F] port 0/0/41
If the receiver is connected to the forbidden port 0/0/41 of the
static multicast group, the receiver cannot receive the multicast
data flow. If the receiver is connected to the member port
0/0/40 of the static multicast group, it can receive the multicast
data flow.
Fault 5: The video jitter appears after enabling IGMP snooping for VOD.
