I have a problem on my uBR 7223 with cable interface bundle.
There are 2 MC14C cards, first - cable bundle master, second - slave.
When I connect cable modem to the slave card cable modem initialization stops at DHCP
stage. The modem sends DHCPDISCOVER, dhcp server answers DHCPOFFER, but cable modem
does not recieve this DHCPOFFER and initialization process stops. The first card in the
bundle (master) works fine. The second card configured without bundle with their own ip addresses
works fine too.
Here is a piece of my cable interace configuration. IP address changed
interface Cable2/0
ip address 172.18.1.1 255.255.0.0 secondary
ip address 212.212.212.33 255.255.255.248 secondary
ip address 10.2.0.1 255.255.0.0
ip access-group 102 in
no ip proxy-arp
ip route-cache flow
no ip mroute-cache
no keepalive
cable bundle 1 master
