Network Management

Hi, I'm not familiar with configuring dscp settings so I'll do my best to explain what we're looking for. 

We have a qsys paging station that isn't connecting due to incorrect dscp settings. They are telling me it needs to have a dscp setting of 34. 

The paging station is connected to Switch 3 in site B on a 6100 Aruba switch, it's routed to the Core (6300) and then route out on a vlan route to a core at site A (3810M) and the qsys core resides on a 6100. 

My question is how do I configure this paging device to receive the proper dscp tag? Does the port directly connected to the paging station need a specific config, and is it good enough for the rest of the ports along the route to have qos trust dscp enabled or do they require more than that? 

All QSYS devices are on VLAN 111 with ip addresses of 10.18.111.x 

Mark the DSCP 34 and then Enable the QoS Trust DSCP on all switches along the path (so you dont have teh DSCP Value overwritten somewhere). 
You should run the "qos trust dscp" command on all ports at Core Site A , Core Site B and Q-SYS Core. 
Also, not very specialized in the exact commands on the 6100 but it should look something like:

qos dscp-map 34 priority 6 <- you map the DSCP value 34 with priority level 6. With this you ensure that DSCP 34 traffic will be treated with higher precedence 

class qos-paging <- This means that where you will place the QoS,  on this interface will match any traffic and then it forces all matched traffic to be tagged with DSCP 34.
match any
action dscp 34

policy qos-paging-policy <- this will create a QoS Policy and attach qos-paging class to ensure traffic matching this qos-paging will get tagged with DSCP 34
class qos-paging
action dscp 34
