Problem Reports
PR 70128
AMAP currently works on the default VLAN for tagged ports only. So, if VLAN 1 (default VLAN) is
disabled, AMAP does not work.
Workaround: When using AMAP, make sure that VLAN 1 (default VLAN) is not disabled.
IP Multicast Switching (IPMS)
Problem Reports
PR 57746
IP Multicast does not support hardware routing with 802.1Q service on an OS7000 series switch.
Workaround: There is no known workaround at this time.
PR 59814
If a multicast routing interface is "Oper-Status" enabled, not just "Admin-Status" enabled, then IPMS is
not be enabled silently on an OS7000 series switch. When the first multicast routing interface moves to the
"enabled" state, IPMS is enabled silently.
Workaround: There is no known workaround at this time.
PR 59907
If IP multicast switching is configured along with group mobility, and multiple clients are configured in
different IP VLANs on the same physical port, multiple copies of the same packet can be routed to that
port causing duplicate delivery of IP multicast traffic on an OS7000 series switch. Note: IP multicast rout-
ing must also be enabled, and multiple clients in different subnets must request the IP multicast traffic
from the same physical port.
Workaround: The CLI command ip multicast hardware-routing may be used to remedy this problem.
This will ensure that only one copy of the packet is forwarded out of any switch port. Please see restric-
tions in using IP multicast hardware routing in the user manual. Note: The route selected for transmitting
the multicast to the port will be selected randomly which may cause problems with the TTL threshold and
multicast scoping.
PR 61590
If one (1) Gb/s multicast traffic, composed of one or several streams, is sent on only one port per EGRESS
NI on an OS7000 series switch, wire rate is not achieved. The speed is limited to around 600Mb/s regard-
less of the packet size.
Workaround: There is no known workaround at this time.
