Interactions
Signaling to other switches or adjuncts can be done through the CLAN and the
processor CLAN function.
If you have an R11 connected to an older system that does not support 802.1p and
802.1Q VLANs on their signaling channels, you can administer it to be in a
network region where these things are administered to
no.
If you decide to ignore the above advice and attempt signaling from a new system
that is using 802.1p and 802.1Q VLANs on their signaling channels to an older
system that does not support these protocols, then whether signaling information
would:
■ Reach the destination, with the network using the frames’ VLAN and
priority information, or
■ Reach the destination, but without having been given VLAN or priority
treatment, or
■ Be dropped, either by the destination or by an intermediate device, depends
on the capabilities of the switches or hubs used in the data network and
how they are configured.
The third possibility, “all frames dropped,” means no signals get through between
the MultiVantage switch and the other device.
