I just purchased some C3KX-SM-10G modules to allow us to do Netflow on our 3750x switches.   I am being told the only transceivers you can install on these modules is fiber.  I typically enable netflow on the uplink to our MPLS for these remote sites.   The uplinks are all copper/RJ45 connections. Does installing these modules enable netflow across the entire switch or only the ports connected to the module? Is it true that the copper RJ45 connections are not compatible? Thanks ... View more

Hello Everyone We in DC we have a primary MPLS circuit and a less expensive point to point VPLS type circuit.  We identify all of our replication traffic via acls and route accross the point to point.  Most ACLs are pretty granular which have source host, destination host and port numbers.  Only one ACL identifies all traffic between 2 hosts.  Since it is all traffic they make good test subjects. With the 2 hosts that send all their traffic between each other using PBR i have tried blocking that path and but hosts do not fall back to primary MPLS.  How do i get this to work?  Config below router ospf 1 redistribute static subnets route-map STATIC-TO-OSPF-MAP  ======= this is to propagate some of our static routes to rest of network. network 10.2.0.0 0.0.255.255 area x   =====ospf being used to advertise networks over MPLS network 172.16.29.0 0.0.0.255 area x network 172.16.40.0 0.0.0.255 area x ACL to identify traffic for PBR ip access-list extended alt_route_archive permit ip host 10.2.x.x host 10.3.x.x Route map route-map alt_route_dc permit 10 match ip address alt_route_evault alt_route_nimble alt_route_sql alt_route_hyperv alt_route_archive set ip next-hop 172.16.x.x I when the above routing does not work i want this to fall back to the MPLS.  I am guessing this is possible because it seems pretty simple but am having hard to finding good documentation.

Hello Everyone We just started doing policy based routing on our network.  We just purchased a layer 2 point to point for replication traffic to offload our MPLS.   I have configured policy based routing on both sides.  Currently we have multiple ACLs identifying multiple types of traffic but only one ACL seems to be working at a time. Site one access-list 151 permit tcp 10.2.2.60 0.0.0.3 10.3.2.60 0.0.0.3 eq 8080 access-list 152 permit tcp any host 10.3.2.30 eq 4214 access-list 153 permit tcp host 10.2.4.90 host 10.3.4.90 eq 12547 access-list 154 permit tcp 10.2.4.150 0.0.0.1 10.3.4.150 0.0.0.1 eq 64327 access-list 155 permit ip host 10.2.4.31 host 10.3.4.31 access-list 156 permit tcp host 10.2.4.157 host 10.3.4.50 range 5022 5026  access-list 156 permit tcp host 10.2.4.158 host 10.3.4.50 range 5022 5026 route-map alt_route_dc permit 10  match ip address 155 151 152 153 154 156  set ip next-hop 172.16.255.2 Policy then assigned to each vlan that is the servers are on. On site 2 we have exactly the reverse configuration. The only traffic I see working correctly is from this ACL access-list 156 permit tcp host 10.2.4.158 host 10.3.4.50 range 5022 5026 All the others have worked when we did them individually ...
