I have an ASA5510 (7.2(4)) with outside interface conn to ISP's Cisco 2610 (10M Ethernet - NOT FASTETHERNET).
Previously a PIX506E was attached to same router. PIX outside was set 'interface ethernet0 10full' and the router's E0/0 was hard set 'full-duplex'.
This link functioned as desired at 10/FULL.
Now when I conn the ASA I cannot get the link to come up at full-duplex. The 2610 is running c2600-i-mz.123-19 IOS.
Any suggestions from the Cisco community?
Phil
