Tagged packet forwarding

If a port is a tagged member of the same VLAN as an inbound, tagged packet received on that port, then the switch forwards the packet to an outbound port on that VLAN.

To enable the forwarding of tagged packets, any VLAN to which the port belongs as a tagged member must have the same VID as that carried by the inbound, tagged packets generated on that VLAN.

CAUTION:

Rate limiting may behave unpredictably on a VLAN if the VLAN spans multiple modules or port-banks.

This also applies if a port on a different module or port-bank is added to an existing VLAN. Hewlett Packard Enterprise does not recommend configuring rate limiting on VLANs that include ports spanning modules or port-banks.

In the following example, ports 2, 3 and 24 form one VLAN, with ports 1 through 24 in the same port-bank. Ports 28, 29 and 32 form a second VLAN. These ports are also in the same port-bank, which includes ports 25 through 48. Rate limiting will operate as expected for these VLANs.
