C2912 LRE Switch port problem

[raju]

Hello,

We have C2912-LRE-XL and the LRE ethernet port is connected with CPE through EPBAX . This distance between LRE Switch & CPE is around 600 meters . From time to time , the LRE port which is connected with CPE goes down and comes automatically for every 2 minutes . The IOS ver is Version 12.0(5)WC2 . The fast ethernet port is ok and stable. Sometimes , the LRE port link goes down more than 5 times per minute . FYI ,Fast eth port & LRE port, both are member of same Vlan. Just pasting the sh logging info . When I change the profile lre-10 for LRE port 6, I don't get green light .

02:03:03: %RTD-1-LINK_FLAP: LongReachEthernet0/6 link down/up 5 times per min

interface LongReachEthernet0/6

lre profile lre-5

This can be caused by several factors

on the line (example noise, crosstalk, bridge-tap)

Please make sure that this line is not affected too much by any other media

example Digital phone, E1 or ADSL in the same bundle.
