Hi Everyone
Can anyone help me in configuring Priority Queueing (QOS) over GRE Tunnels
We have access locations (Site Router 1841) connected to Aggregation Router (Cisco 3845) using RF Radio Link as Primary and Leased Line as Backup
GRE's were created for RF Link (terminated on Access Router - Fast Ethernet Port) inorder to sense that RF Link is down (Using Keepalives) and traffic is routed via backup link (Leased Line)
we are using static Routing
Now we want to implement QOS -- and infact have implemented Priority Queueing for those access sites which are having Leased Line as Primary and ISDN as Backup and while trying to implement the same for those access sites which are having GRE tunnels created , the tunnel interface doesnot support priority-group command
Kindly let me know how to overcame this obstacle

With logical interfaces such as a GRE tunnel interface you need to use a hierarchical policy, see if this link helps -

We have implemented Priority Queueing on CE1 time slots
the configuration is as follows
R01#sh int Se1/0:5
Serial1/0:5 is up, line protocol is up
Hardware is DSX1
Description: *** 64Kbps to Site XXX ***
Internet address is 172.16.100.50/30
MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec,
reliability 255/255, txload 3/255, rxload 1/255
Encapsulation PPP, LCP Open
Open: CDPCP, IPCP, loopback not set
Last input 00:00:25, output 00:00:01, output hang never
Last clearing of "show interface" counters 03:25:21
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 1
Queueing strategy: priority-list 1
Output queue (queue priority: size/max/drops):
high: 0/20/1, medium: 0/40/0, normal: 0/60/0, low: 0/80/0
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 1000 bits/sec, 1 packets/sec
4928 packets input, 472323 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
4959 packets output, 608985 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
Timeslot(s) Used:7, Transmitter delay is 0 flags
Access list has been defined as follows
Extended IP access list 102
permit tcp any any eq telnet (19567 matches)
permit tcp host 172.31.0.24 any (443058 matches)
permit tcp host 172.31.0.4 any (212716 matches)

permit tcp host 172.19.125.37 any (30 matches)
permit tcp host 172.31.0.240 any (148804 matches)
and when we execute command on Router as Show interface Serail1/0:5 summary
R01#sh int Se1/0:5 summary
*: interface is up
IHQ: pkts in input hold queue IQD: pkts dropped from input queue
OHQ: pkts in output hold queue OQD: pkts dropped from output queue
RXBS: rx rate (bits/sec) RXPS: rx rate (pkts/sec)
TXBS: tx rate (bits/sec) TXPS: tx rate (pkts/sec)
TRTL: throttle count
Interface IHQ IQD OHQ OQD RXBS RXPS TXBS TXPS TRTL
---------------------------------------------------------------------
* Serial4/0:6 0 0 0 200 3300 0 0 0 0
NOTE:No separate counters are maintained for subinterfaces
Hence Details of subinterface are not shown
Can anyone help us in understanding what is the meaning of NOte " No separate counters are maintained for subinterfaces
Hence Details of subinterface are not shown "
Do we require to do some additional configuration for time slots
