For the VSP 7000, it is important to not enable the filter-untagged-frame option on the IST port members.
Prior to releases to 10.4.0, the default PVID of all IST ports must be the primary B-VLAN ID. This will happen
automatically providing SPB is enabled first prior to enabling the IST. You can check the default PVID by
entering the ACLI command show vlan interface info <port list>. To manually set the default PVID on the
IST ports, use the ACLI command vlan ports <port list> pvid <1-4096>.
Starting with release 10.4.0, the PVID will automatically be set with the secondary BVLAN ID on the primary
SMLT node and with the primary BLAN ID on the secondary SMLT node. This will also occur automatically
when upgrading from release 10.3.x to 10.4.0. The output from the CLI show vlan interface
<port> command will display either the primary or secondary PVID depending on which switch you are
connected to.
Also, it is recommended to not enable VLACP on the IST and layer 3 routing is not supported with SPBM.
16.7SLPP Guard
SLPP Guard is supported on the ERS 3500, ERS 4000, ERS 5000, ERS 5900, and VSP 7000
SLPP can enabled on the core bridges and in turn SLPP Guard can be enabled on the switch for
local port loop detection
Because of this feature, SLPP can be enabled on the core SPB bridges and in turn
allowing SLPP Guard to be enabled on the ERS 4800
Only enable SLPP on the C-VLAN on the core SPB bridges
Do not enable SLPP Packet Rx on core NNI ports
Never want to take these ports down
