Load Balancing?
by rassylkaformazaj＠ukr.net 07 Feb '05

07 Feb '05

Hello all, Есть необходимость настроить что-то вроде кластера. Несколько WEB серверов, на которые нужно равномерно разбрысывать трафик. Неподскажите ли какие есть варианты как это сделать? Какие плюсы/минусы? Интересует возможность балансировки на основании sessionid. -- С уважением, мазай.

�� WS-2950-24 ...

Добрый день, Есть 2611 связанная с 2950-24 через dot1.q trunk между ними. Возникла непонятная проблемка на 2950-24. В какой-то произвольный момент времени на 2950-24 перестают ходить пакеты в сторону 2611. Причем именно 2950-24 перестает посылать пакетики. На вход же 2950-24 (от 2611) пакетики продолжают исправно поступать. Вот как это выглядит: xxxxxx-sw#sh int fa0/24 FastEthernet0/24 is up, line protocol is up (connected) Hardware is Fast Ethernet, address is yyyy.yyyy.ac58 (bia yyyy.yyyy.ac58) Description: -=[ Trunk to E0/1 on xxxxxx.donbass.net (rezerv) ]=- MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Half-duplex, 10Mb/s input flow-control is off, output flow-control is off ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output 00:00:00, 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) 30 second input rate 0 bits/sec, 0 packets/sec 30 second ouxtput rate 0 bits/sec, 0 packets/sec 1775 packets input, 1831423 bytes, 0 no buffer Received 27 broadcasts, 89 runts, 0 giants, 0 throttles 89 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 1 multicast, 0 pause input 0 input packets with dribble condition detected 10605 packets output, 5466867 bytes, 0 underruns 0 output errors, 75 collisions, 1 interface resets 0 babbles, 0 late collision, 448 deferred 0 lost carrier, 0 no carrier, 0 PAUSE output 0 output buffer failures, 0 output buffers swapped out xxxxxx-sw# sh int fa0/24 FastEthernet0/24 is up, line protocol is up (connected) Hardware is Fast Ethernet, address is yyyy.yyyy.ac58 (bia yyyy.yyyy.ac58) Description: -=[ Trunk to E0/1 on xxxxxx.donbass.net (rezerv) ]=- MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Half-duplex, 10Mb/s input flow-control is off, output flow-control is off ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output 00:00:00, 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) 30 second input rate 0 bits/sec, 0 packets/sec 30 second ouxtput rate 0 bits/sec, 0 packets/sec 1816 packets input, 1855189 bytes, 0 no buffer Received 27 broadcasts, 89 runts, 0 giants, 0 throttles 89 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 1 multicast, 0 pause input 0 input packets with dribble condition detected 10605 packets output, 5466867 bytes, 0 underruns 0 output errors, 75 collisions, 1 interface resets 0 babbles, 0 late collision, 448 deferred 0 lost carrier, 0 no carrier, 0 PAUSE output 0 output buffer failures, 0 output buffers swapped out xxxxxx-sw#cle counters fastEthernet 0/24 Clear "show interface" counters on this interface [confirm] xxxxxx-sw#sh int fa0/24 FastEthernet0/24 is up, line protocol is up (connected) Hardware is Fast Ethernet, address is yyyy.yyyy.ac58 (bia yyyy.yyyy.ac58) [skip] Last clearing of "show interface" counters 00:00:10 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue :0/40 (size/max) 30 second input rate 0 bits/sec, 0 packets/sec 30 second ouxtput rate 0 bits/sec, 0 packets/sec 6 packets input, 3410 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 watchdog, 0 multicast, 0 pause input 0 input packets with dribble condition detected 0 packets output, 0 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 В логах ничего аномального не наблюдается: xxxxxx-sw# sh logg [skip] *Mar 1 02:00:25.343 EET: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to down .Jan 28 17:51:32.050 EET: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to up .Jan 28 17:51:32.062 EET: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up MAC 2611 на порту 2950-24 присутствует: xxxxxx-sw#sh mac-address-table address zzzz.zzzz.db61 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 5 zzzz.zzzz.db61 DYNAMIC Fa0/24 2 zzzz.zzzz.db61 DYNAMIC Fa0/24 3 zzzz.zzzz.db61 DYNAMIC Fa0/24 4 zzzz.zzzz.db61 DYNAMIC Fa0/24 1 zzzz.zzzz.db61 DYNAMIC Fa0/24 Total Mac Addresses for this criterion: 5 xxxxxx-sw#sh ip arp Protocol Address Age (min) Hardware Addr Type Interface Internet aaa.bbb.ccc.17 8 zzzz.zzzz.db61 ARPA Vlan1 Internet aaa.bbb.ccc.18 - yyyy.yyyy.ac40 ARPA Vlan1 xxxxxx-sw#ping aaa.bbb.ccc.17 Type escape sequence to abort.

Причем когда порт находится в access mode пакеты в него тоже не уходят. :((( Думали что порт на 2950 битый. Переключили в другой порт 2950 - не помогло. Шнурки тоже попытались менять.

Hello ! По поводу проблем с карлсонами. Обрати внимание, какие именно карлсоны стоят на том каталисте - с тремя или с двумя проводочками. Возможно, ты попал на т.н. refurbished каталист, у которого родные фаны с тахометром заменены обычными.

саппорт & ICQ

Hi All! А никто не встречал такого решения - типа один ICQ аккаунт расшаренный на нескольких человек, для саппорта, что бы клиентам давать один UIN а получали и отвечали несколько саппортеров, желательно с подписью кто ответил. Понятно, что можно взять напильник и заточить jit-транспорт для jabber, но хотелось бы обойтись.
