我单位4台2950用了WS-X3500-XL模块堆叠,为什么在堆叠的端口上只能用半双工?就不能使用全双工命令.
下面是这个端口的情况

GigabitEthernet0/2 is up, line protocol is up (connected)
  Hardware is Gigabit Ethernet, address is 0014.6a5e.a932 (bia 0014.6a5e.a932)
  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Half-duplex, 1000Mb/s, media type is CX
  input flow-control is off, output flow-control is off
  ARP type: ARPA, ARP Timeout 04:00:00
  GigaStack module(0.2) in GBIC slot. link1 is up, link2 is redundant link
  Last input 00:00:00, output 00:00:06, output hang never
  Last clearing of "show interface" counters never
  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 1365000 bits/sec, 334 packets/sec
  5 minute output rate 75000 bits/sec, 16 packets/sec
     801911678 packets input, 179590593 bytes, 0 no buffer
     Received 53452042 broadcasts (0 multicast)
     0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 watchdog, 39039112 multicast, 0 pause input
     0 input packets with dribble condition detected

哪位大侠给看看,小弟我先谢过啦

GigaStack GBIC利用基于硬件的、独立的堆叠总线，在点对点的配置中可提供最大2Gbps的转发速率，或在交换机的菊花链配置中提供半双工 1Gbps的转发带宽。
