Hello,
I have 7206VXR acting as LNS. Clients received config via Radius.
I am trying to set QoS and priorize ping (for testing) :
access-list 150 permit icmp any any
I shape the Virtual-Access interface in parent class :
policy-map Parent_test_1
class class-default
shape average percent 90
service-policy Child_test_1
And priorize ping in child class :
policy-map Child_test_1
class ping
priority percent 99
class class-default
fair-queue
interface Virtual-Access3
mtu 1492
bandwidth 1677
ip vrf forwarding TEST
ip unnumbered Loopback0
no ip redirects
no ip proxy-arp
ip tcp adjust-mss 1400
load-interval 60
random-detect
service-policy output Parent_test_1
Interface Vi3 is a client connected via PPP/L2TP session.
When congestion occurs, packets are matching the queue :
Class-map: ping (match-all)
11029 packets, 3518323 bytes
1 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 150
Queueing
Strict Priority
Output Queue: Conversation 72
Bandwidth 99 (%)
Bandwidth 1493 (kbps) Burst 37325 (Bytes)
(pkts matched/bytes matched) 366/83117
(total drops/bytes drops) 0/0
But these matched packets are never received by the client.
Packets in the queue are lost and i don't understand where...
