Input queue size have negative figure


I have a router work in tunnel. When I show interface tunnel, in the input queue, size have a negative figure. May I know why and how should I solve it. Below is one example.

Tunnel113 is up, line protocol is up

Hardware is Tunnel

Description: SJ to PG

Internet address is

MTU 1514 bytes, BW 9 Kbit, DLY 500000 usec,

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

Encapsulation TUNNEL, loopback not set

Keepalive not set

Tunnel source (FastEthernet0/0), destination

Tunnel protocol/transport GRE/IP, key disabled, sequencing disabled

Tunnel TTL 255

Checksumming of packets disabled, fast tunneling enabled

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

Last clearing of "show interface" counters 00:50:42

Input queue: -995291044/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo

Output queue: 0/0 (size/max)

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

5 minute output rate 0 bits/sec, 1 packets/sec

33251 packets input, 6865110 bytes, 0 no buffer

Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

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

Re: Input queue size have negative figure

The problem may be due to router running older version of IOS
