QOS for a Destination-ip in Cisco IOSXE

[titusroz03]

Hi All,

We have a URL which resolves to particular public ip and performance of that website is slow than expected from our office . We have a P2P link from office to DataCentre and from DataCentre it exits to internet. We observed the performance was comparatively better from Data center connected machine and open Internet rather than office network.

I need some knowledge on how we can prioritize through QOS on the P2P link towards DC,already we have QOS for EF,AP and VC traffic .Along with this I need the URL traffic should also be prioritized.Can anyone help me with this..?

Below policy is applied on user connected interface as input

Service-policy input: Prod-QoS-Q4-2022_Policy & marking.

Below policy is applied on Egress interface as output.

HK_OUT_QOS

[Joseph W. Doherty]

Uh-huh, but can you answer my prior reply's question?

[titusroz03]

Below is the input and output of the interface

[Joseph W. Doherty]

Yes, and very helpful, as I may see your issue.

"Input" policy should be applied to LAN facing interface(s).  "Output" should be applied to WAN facing interface.

You have both policies applied to g2/0/35, correct?

[titusroz03]

@Joseph W. Doherty Yes..Have applied both on LAN interface, because initially the out was applied on WAN interface and LAN had input only, but it didn't make difference and there was lot of drops in WAN. So I suspected whether wan interface is not acting much efficiently on OUT qos hence applied it on Access interfaces as well.

[Joseph W. Doherty]

What's g2/0/35, LAN or WAN?

That was the only interface with policies when/for the g2/0/35 stats?

What concerns me with the g2/0/35 stats, no matches on non default classes.

BTW QoS doesn't always/often preclude drops just allow preference on what will be dropped first.

Input capture increases on the interface
