Já tentei espaço com bits de 120000.
Não funcionou

[leandrogrilli]

Sim. Desbloquiei um 7600.

[leandrogrilli]

Nada. Dou o comando de parada nos momentos que a documentação diz pra fazer e nada acontece.

[leandrogrilli]

Sim

To enable I/O Mode 1, use the sdm prefer 2 command, and reload the system.

I/O Mode 2

In I/O Mode 2 the following ports are available:

Eight GigabitEthernet ports 0/1 to 0/8
Four TenGigabitEthernet ports 0/1 to 0/4
Management port GigabitEthernet 0/0

---

To enable I/O Mode 2, use the sdm prefer 4 command and reload the system.

Limitations

TenGigabitEthernet port 0/1 can be bundled only with TenGigabit port 0/2 for Etherchannel (and vice-versa).

TenGigabit port 0/3 can be bundled only with TenGigabit port 0/4 for Etherchannel (and vice-versa).

I/O Mode 3

In I/O Mode 3 the following ports are available:

16 GigabitEthernet ports
Three TenGigabitEthernet ports
Management port GigabitEthernet 0/0

Segundo a cisco estas podem ser as causas.
Inferior Speed/Duplex for the Amount of Traffic

Your network can send too many packets through this port for the port to handle at its current speed/duplex setting. This can happen where you have multiple high-speed ports flowing to a single (usually slower) port. You can move the device that hangs off this port to faster media. For example, if the port is 10 Mbps, move this device to a 100 Mbps or Gigabit port. You can change the topology to route frames differently.

Congestion Issues: Segment Too Busy

If the segment is shared, other devices on this segment can transmit so much that the switch has no opportunity to transmit. Avoid daisy-chained hubs whenever possible. Congestion can lead to packet loss. Packet loss causes retransmissions at the transport layer which in turn causes users to experience latency at the application level. You can upgrade10Mbps links to 100Mbps or Gigabit Ethernet links when possible. You can remove some devices from crowded segments to other less populated segments. Make congestion avoidance a priority on your network.

Applications

At times the traffic transmission characteristics of the applications used can lead to output buffer problems. NFS file transfers that come from a Gigabit attached server that uses user datagram protocol (UDP) with a 32K window size is one example of an application setting that can bring out this type of problem. If you have checked or tried the other suggestions in this document (checked speed/duplex, no physical errors on the link, all the traffic is normal valid traffic, and so on), then reducing the unit size that is sent by the application can help alleviate this problem.

Alguém concorda?
problemas quando o trafego vem de duas portas distintas e precisa ser encaminhado para apenas uma.

[leandrogrilli]

Detalhe.
Tenho duas interfaces de ME-3600( Gi 0/23 e 0/24) conectadas a operadora(ISP/BGP). E a Gi 0/22 conectada ao 3400( trunk – rede interna).
Quando somente um link de entrada esta ativo ( 0/23 ou 0/24) não há OutDiscards na pora 0/22 do 3600.
Mas quando ativo outro link ( 0/23 e 0/24 juntos) começa a aparecer OutDiscards na 0/22 virada para o 34000.
Não importando o volume de trafego:
Se eu tenho 100Mb entrando na 0/23 ou 0/24 e 100Mb saindo pela 0/22 nao há OutDiscards.
Mas se eu tenho 50Mb entrando pela 0/23 + 50 MB entrando pela 0/24 e 100Mb saindo pela 0/22 o OutDiscards incrementa rapidamente.

[leandrogrilli]

Sim Sao.
Já aumetei o MTU do ME-3600 para 9000 e coloquei “system mtu jumbo” no ME-3400.
O cenario continua o mesmo.

[leandrogrilli]

Quando ativo a nova interface fica dado OUTDsicart

Antes de ativas a segunda sessão BGP.

[leandrogrilli]

A configuração de BGP é bem simples.
Cada ip de borda com a operadora é colocado em um a interface vlan e a porta do switch L3 ~e acossiada a vlan correspondente.
Já tentei associar o IP direto a porta. Mas acontece a mesma coisa.

configuracao de BGP é somente os neighbors e mais nada.
A operadora envia somente rota zero.

Em relação a ser físico? não perde pacote pro primeiro switch da rede interna antes de eu ativar a segunda sessão no router de borda.

[leandrogrilli]

Na verdade pedir pro pessoal do link parar de me anunciar pro chache do google.

[leandrogrilli]

Obrigado.

[leandrogrilli]

Não… desculpe… Neste momento estava sem filtro.

[leandrogrilli]

[leandrogrilli]

Resolvido.
O questão era bem mais simples.
Lembra que disse que a borda tinha 2 links para a rede interna, para dar 2G.
Intaum. Eu tava fechando vizinhança com um desses dois endereços, porem como é multi-hoop hora ele respondia por uma e hora por outra.
Fixei o update-source no router(MK) e o problema não existe mais.
Obrigado a todos.
