General Procurve VLAN Question

Please do not spend much time on the validity of my example environment, I am just trying to illustrate my question.

---->
Example environment(Procurve 5412zl All ports are 1Gbps [J8702A for example]):

VLAN 50 (DATA1) - ports A1-A24
VLAN 100 (DATA2) - ports B1-B24

The two VLAN's are connected by a shared tagged port: C1
--->
Question: In such an environment with two VLANS that are connected by a shared tagged port, are there any implied throughput restrictions? If the modules used are 1Gbps, does this mean that all traffic flowing from VLAN 50 to VLAN 100 will be capped at 1Gbps?

Ho ho ho,
yes chris, if the 5412 isn't doing the routing, but a device connected on port c1 then the vlans can only communicate with 1Gbps, if c1 is a 1Gbps port.

Re: General Procurve VLAN Question

what about if the 5412 is doing the routing?

Hi Chris,

if your 5400 is routing between the VLANs then you have no restrictions in terms of link speed of a single interface. There is (in theory) a routing performance of 576 Gbit/sec on the 5412.
See the reviewers guide for details about the architecture:
