[inet-admins] STAC компрессия между CISCO & Inter Express Router ...

[Yury Yaroshevsky <yk@donbass.net>]

Есть CISCO 2611 и Intel Express Router 9100.
Между ними настроен FR.

вот конфигурация интерфейса со стороны CISCO:

interface Serial0/0
 no ip address
 encapsulation frame-relay IETF
 no ip route-cache
 no ip mroute-cache
 no fair-queue
 clockrate 128000
 frame-relay lmi-type ansi
 frame-relay intf-type dce

interface Serial0/0.1 point-to-point
 ip unnumbered Loopback0
 no ip route-cache
 no ip mroute-cache
 frame-relay interface-dlci 129 IETF protocol ip 10.0.1.1
 frame-relay payload-compression FRF9 stac software

На Intele на этом PVC включен Data Compression - STAC

Вот что происходит на CISCO (debug compress) при попытке опустить/поднять
интерфейс:

00:07:56: frf9_DLCIStatusChange dlci: 129
00:07:56: frf9_DLCIStatusChange: closing hardware
00:07:58: %LINK-5-CHANGED: Interface Serial0/0, changed state to 
administratively down

00:08:19: frf9_monitorNegotiation: re-sending mode 1 request
00:08:22: frf9_monitorNegotiation: re-sending mode 1 request
00:08:25: frf9_monitorNegotiation: re-sending mode 1 request
00:08:28: Serial0/0:FRF9: negotiation retry limit exceeded!

Хотя после этого sh compress говорит:

Router#sh compress
 Serial0/0 - DLCI: 129
        Software compression enabled
        uncompressed bytes xmt/rcv 0/0
        compressed   bytes xmt/rcv 0/0

        10 min avg ratio xmt/rcv 0.000/0.000
        no bufs xmt 0 no bufs rcv 0
        resyncs 0
      Additional Stacker Stats:
      Transmit bytes:  Uncompressed =        0 Compressed =          0
      Received bytes:  Compressed =          0 Uncompressed =        0

На IP 12.3.5 при том же debug, sh compress показывал что компрессия не включена.

Кто-нибудь использует STAC компрессию между CISCO и Intel (на FR PVC) ?
Какие рекомендации будут по версии IOS-са и настройкам?
