I have an UE450 hooked to a Cisco Catalyst 55xx box, many problems
like you describe until the Cisco's firmware was updated. Ask whomever
maintains the Cisco if it has the latest firmware.
I fought this thing for a couple of weeks straight, very frustrating
indeed. The funny thing was one interface (hme1) worked perfectly
and the built in interface (hme0) did not, it seemed to be a problem
with the Sun box because it followed the interface and not the port
on the Cisco we used, but after the firmware upgrade all worked as
advertised.
As other posters have suggested, it probably is a good idea to force
the Sun and the Cisco to fixed parameters and avoid autonegotiation.
My boxes have this in their /etc/system file:
**
** Force 100MB Full duplex on all hme interfaces
**
set hme:hme_adv_autoneg_cap = 0
set hme:hme_adv_100T4_cap = 0
set hme:hme_adv_100fdx_cap = 1
set hme:hme_adv_100hdx_cap = 0
set hme:hme_adv_10fdx_cap = 0
set hme:hme_adv_10hdx_cap = 0
HTH,
