Jabber on all phone ports

All of my 3560 ports connected to phones (7940/42/60/70/71) are showing continuous 50pps output towards the phones. I've turned off GARP but still no improvement.

Although most of these phones have PC's attached, the data VLAN is not affected.

I can't get an ethereal until tomorrow but on the off chance anyone has seen this before ?

Here's a sh int from an affected interface :-

FastEthernet0/7 is up, line protocol is up (connected)

Hardware is Fast Ethernet, address is 001d.e516.6109 (bia 001d.e516.6109)

MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

Full-duplex, 100Mb/s, media type is 10/100BaseTX

input flow-control is off, output flow-control is unsupported

ARP type: ARPA, ARP Timeout 04:00:00

Last input 00:00:50, output 00:00:00, output hang never

Last clearing of "show interface" counters 00:00:01

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo

Output queue: 0/40 (size/max)

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 90000 bits/sec, 51 packets/sec

0 packets input, 0 bytes, 0 no buffer

Received 0 broadcasts (0 multicasts)

0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

0 watchdog, 0 multicast, 0 pause input

0 input packets with dribble condition detected

104 packets output, 22640 bytes, 0 underruns

0 output errors, 0 collisions, 0 interface resets

0 babbles, 0 late collision, 0 deferred

0 lost carrier, 0 no carrier, 0 PAUSE output

Appreciate any ideas.

I had the similar problem like you now.

The problem was in Microsoft Load Balansing.

The Microsoft guys have tried to do load balansing but it didn't work and there was a lot of multicat packets in that VLAN.

After we have removed these servers, everything was OK.

Maybe this can help you?
