Hi everybody ...we are having a really strange issue between a WAE-574 inline port and a WS-C3524-XL...
We already tried to change the switch port , to change the cable , to upgrade IOS on the switch..
But the only solution was to change the switch with another model ( Ex. Cisco 3560) !!
Anyway ...Now customer would like to know why ..
This is the scenario :
WAAS ver 4.1.5
Router 2811 Fa0/0 ---> WAE Inlineport1/1/wan - WAE inlineport 1/1lan---- Fa0/4 Switch WS-C3524-XL
Speed and duplex is forced in every point at full/100. Cable are correct ( Crossover Router to WAE , Straight WAE to Switch)
The switch port is configured correctly and there are no errors on the interface :
SWITCH#sh interfaces fastEthernet 0/4
FastEthernet0/4 is up, line protocol is up
Hardware is Fast Ethernet, address is 0009.437c.3fc4 (bia 0009.437c.3fc4)
Description: ** Router 2 BT **
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,

Now link come up and down and we have this error on the WAE-574 :

We have seen that some counters increments :
wa-574#sh int inlineport 1/1/lan
Device name : eth3. Bypass slave interface.
