Hi Guys n Gals,


I am having an issue with applying a route-map to an SVI to route certain traffic via a redundant link.


The route-map is configured as follows,


access-list 101 permit ip host 10.2.10.14 host 10.1.10.10

access-list 101 permit ip host 10.2.10.14 host 10.1.10.11

access-list 101 permit ip host 10.2.10.14 host 10.1.10.12

route-map CLAN_LON permit 10

match ip address 101

set ip next-hop 192.168.102.20


Very simple as far as I am concerned.


The hardware is a WS-C3750G-24TS running c3750-advipservicesk9-mz.122-25.SEB4.


When applying to the SVI the command is accepted, but not applied. I have checked the usual things such as case etc.

When first configured it did apply and was working ok, but vanished from the configuration about 3 months ago.

I have checked the bug tool kit and there is a bug on the version which does not write the PBR function into hardware, but this was working. Have rebooted the device in case the bug had caused it, but it still would not apply.


Has anyone experienced this issue also? At the moment I am going along the lines of a IOS upgrade, but I would like to see if it is something else first as this would require scheduling/more downtime etc....


Thanks

Hi,


Not come across these before.


So in default;

Switch# show sdm prefer

The current template is "desktop default" 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: 6K

number of igmp groups + multicast routes: 1K

number of unicast routes: 8K

number of directly connected hosts: 6K

number of indirect routes: 2K

number of policy based routing aces: 0

number of qos aces: 512

number of security aces: 1K


Does this mean that no memory is allocated to the PBR process and thus will not work...?


If SDM is set to prefer routing;


Switch# show sdm prefer routing

"aggregate 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: 6K

number of igmp groups + multicast routes: 1K

number of unicast routes: 20K

number of directly connected hosts: 6K

number of indirect routes: 14K

number of policy based routing aces: 512

number of qos aces: 512

number of security aces: 1K



Resource will be allocated?


Thanks


Andy

It's TCAM entry allocation instead of memory but you got the idea.
