Cisco 3560 %PLATFORM_UCAST-6-PREFIX:

Доброе время суток.

В логах начал получать сообщения вида :

 

%PLATFORM_UCAST-6-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix

 

О чем говорит оно?

 

Спасибо.

слишком много пользователей/маршрутов

посмотреть текущую ситуацию можно командами типа show platform tcam utilization или show platform ip unicast failed route

на деле грозит кривой маршрутизацией и/или включением частичного процесс свитчинга, с большими дропами и rtt

Приведи выводы команд свыше, потом сделай вот это

 

WS-C3750G-48TS-S#show sdm prefer

The current template is "desktop routing" template.

The selected template optimizes the resources in

the switch to support this level of features for

8 routed interfaces and 1024 VLANs.

 

number of unicast mac addresses: 3K

number of IPv4 IGMP groups + multicast routes: 1K

number of IPv4 unicast routes: 11K

number of directly-connected IPv4 hosts: 3K

number of indirect IPv4 routes: 8K

number of IPv4 policy based routing aces: 0.5K

number of IPv4/MAC qos aces: 0.5K

number of IPv4/MAC security aces: 1K

 

 

WS-C3750G-48TS-S(config)#sdm prefer ?

access Access bias

default Default bias

dual-ipv4-and-ipv6 Support both IPv4 and IPv6

ipe IPe bias

routing Unicast bias

vlan VLAN bias

 

 

Ну и выбери себе профиль sdm под твои задачи. Будет нужна перезагрузка.
