"etherchannel между catalyst 3550 & netgear GS724T" Отправлено taphy, 18-Фев-09 00:09
Доброго времени суток, помогите советом где покрутить (если вообще возможно..) Есть netgear сидящий за catalyst 3550 (подключение через etherchannel) линк ведет себя не стабильно - потерь нет, но странные задержки наблюдаются и это сильно мешает: ping to catalyst (здесь все стабильно): 64 bytes from 192.168.3.3: icmp_seq=1 ttl=255 time=0.617 ms 64 bytes from 192.168.3.3: icmp_seq=2 ttl=255 time=0.623 ms 64 bytes from 192.168.3.3: icmp_seq=3 ttl=255 time=0.630 ms 64 bytes from 192.168.3.3: icmp_seq=4 ttl=255 time=0.637 ms --- 192.168.3.3 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3999ms rtt min/avg/max/mdev = 0.617/0.626/0.637/0.032 ms, pipe 2 ping to netgear (провалы периодические): 64 bytes from 192.168.3.2: icmp_seq=2167 ttl=64 time=3.97 ms 64 bytes from 192.168.3.2: icmp_seq=2168 ttl=64 time=3.98 ms 64 bytes from 192.168.3.2: icmp_seq=2169 ttl=64 time=45.4 ms 64 bytes from 192.168.3.2: icmp_seq=2170 ttl=64 time=86.9 ms 64 bytes from 192.168.3.2: icmp_seq=2171 ttl=64 time=197 ms 64 bytes from 192.168.3.2: icmp_seq=2172 ttl=64 time=4.00 ms --- 192.168.3.2 ping statistics --- 2205 packets transmitted, 2198 received, 0% packet loss, time 2206039ms rtt min/avg/max/mdev = 3.814/21.647/394.499/44.164 ms, pipe 2 конфига на циске : interface FastEthernet0/23 description downlink to netgear sw switchport trunk encapsulation dot1q switchport trunk native vlan 254 switchport trunk allowed vlan 252-254,2300 switchport mode trunk no ip address duplex full speed 100 channel-group 1 mode on ! interface FastEthernet0/24 description downlink to netgear sw switchport trunk encapsulation dot1q switchport trunk native vlan 254 switchport trunk allowed vlan 252-254,2300 switchport mode trunk no ip address duplex full speed 100 channel-group 1 mode on interface Port-channel1 switchport trunk encapsulation dot1q switchport trunk native vlan 254 switchport trunk allowed vlan 252-254,2300 switchport mode trunk no ip address duplex full cs3550-QS#sho interfaces Port-channel 1 Port-channel1 is up, line protocol is up (connected)   Hardware is EtherChannel, address is 0011.20a9.8498 (bia 0011.20a9.8498)   MTU 1500 bytes, BW 200000 Kbit, DLY 100 usec,      reliability 255/255, txload 1/255, rxload 1/255   Encapsulation ARPA, loopback not set   Full-duplex, 100Mb/s   input flow-control is off, output flow-control is off   Members in this channel: Fa0/23 Fa0/24   ARP type: ARPA, ARP Timeout 04:00:00   Last input never, output never, output hang never   Last clearing of "show interface" counters 00:14:29   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 1000 bits/sec, 1 packets/sec      1487 packets input, 318025 bytes, 0 no buffer      Received 1 broadcasts (0 multicast)      0 runts, 0 giants, 0 throttles      0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored      0 watchdog, 1 multicast, 0 pause input      0 input packets with dribble condition detected      2285 packets output, 237158 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      0 output buffer failures, 0 output buffers swapped out на netgear: trunk-group 4 ports 23 and 24 statistics on netgear's trunk: ID Tx    Rx  Tx-Error Rx-Error ID Tx Rx   Tx-Error Rx-Error 23 1684  315 0        0        24 0  2204 0        0 (странно что на 24 порту Tx=0 и большая разница по Rx на обоих портах..)
