If you're having trouble negotiating DHCP with a cable modem provider, it may be because the provider is looking for a Windows-specific parameter in the DHCP request. Set up a Windows box and sniff the negotiation, then compare it with what your Solaris box does. You may need to use the ISC DHCP client to be able to set the parameters you need to suit the cable modem DHCP server.
My cable provider here has one-mac address dhcp leases, so switching network cards has to wait until the lease expires, which takes 4 hours for this ISP.
That's an independent issue. I have had to work around a cable provider's idiosyncratic DHCP server's tacit requirement that host-name be set, and that vendor-class-identifier set to "MSFT 5.0". The stock Solaris DHCP client could not generate a suitable DHCP request. The same provider used to have a long arp cache that resulted in delays of up to an hour when switching ethernet cards, along the lines of what you describe.
