DSCP settings on core switch

[james_pethigal]

First off...  Thanks everybody who has been answering my questions about the ICX 7750 campus network I inherited!

Been a great resource while I come up to speed on Ruckus.

Question is:   My campus switches have basically the below DSCP/LLDP Voice settings on all of them.

 lldp med network-policy application voice tagged vlan XXX priority 7 dscp 48 ports ethe 1/1/1 to 1/1/5 ethe 1/2/1

lldp run

The core 7750 stack they connect into & is also connected to the PBX has no LLDP/DSCP settings.

That an issue?  We do have intermittent jitter... but not a lot.

 Should I mirror the LLDP settings on the core or will a simple “trust dscp” be sufficient?

Cheers!
