I have a router with an ADSL connection to an ISP. The router has a single public IP address that gets negotiated on connection (PPPoA Dialer Interface), everything internal is NAT'd with this IP address. I have enabled Netflow exporting and am receiving stats on my receiver application OK.
The problem I have is I see 3 interfaces reporting stats - Ethernet0, Dialer1 and Virtual-Access2. Ethernet0 is showing ingress and egress stats, whilst Dialer1 is showing only Egress and Virtual-Access is only showing Ingress. I believe this is down to the way the traffic flows with the Dialer interface. If I do a 'show ip flow cache' I never see the Dialer1 interface as a source, although it is a destination. Sources are either Ethernet0 or Virtual-Access2. Dialer1 is bound to Virtual-Access2 therefore inbound packets over the DSL interface arrive on Virtual-Access2 with a destination of Ethernet0. Internally originated packets arrive on Ethernet0 with a destination of Dialer1.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
