Ingress filter like on EOS also on EXOS?


Userlevel 2
Hi all,

Can an ingress filter be implemented on EXOS? In fact it is a basic security feature IMHO because creating tagged packets to trash a VLAN you usually don't have access to is not that hard...

To remind everyone: ingress filter on EOS = a packet ingressing the port with a certain tag will only be accepted if the VLAN from the tag is present in the port's egress VLAN list.

Thanks,
Marki

EXOS by default works as EOS does with activated ingress-filter.

Hi Jeronimo,

EXOS already does this by default.

Have you seen an issue where an EXOS switch is passing traffic that it should not based on the VLAN config on a port? If so, please open a case with GTAC.

Thanks, no I haven't seen anything. It's a pre-sales thing 😉
