hi all:
i have a cisco 3750 fastethernet switch connecting to a juniper 4200, with
portchannel on cisco side and aggregated interface juniper side. the cisco side
shows as "connected" but juniper side remain down. could anyone give me some
ideas? no lacp activated on both side.
for cisco:
cisco-3750#sh int fast1/0/9
FastEthernet1/0/9 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 0018.b99f.5d8b (bia 0018.b99f.5d8b)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
cisco-3750#sh interfaces por10
Port-channel10 is up, line protocol is up (connected)
Hardware is EtherChannel, address is 0018.b99f.5d8c (bia 0018.b99f.5d8c)
MTU 1500 bytes, BW 200000 Kbit, DLY 100 usec,

Encapsulation ARPA, loopback not set
Full-duplex, 100Mb/s, link type is auto, media type is unknown
input flow-control is off, output flow-control is unsupported
