Gigabit Ethernet Interfaces
No interoperability configurations required between the platforms
10GE ports on CISCO ME3600X/3800X operating at 1Gig rate
On CISCO ME3600X/3800X the TenGig Ethernet ports can operate at 1 Gig when 1 Gig SFPs are plugged
in. In such scenarios additional interoperability commands are required.
Auto negotiation is disabled by default on Gigabit Ethernet Interfaces in CISCO ASR 9000.
Auto negotiation is enabled by default on Gigabit Ethernet Interfaces in CISCO ME3600X/3800X and
CISCO ASR 903.
To establish the link between CISCO ASR 9000 and CISCO ME3600X/3800X, enable auto negotiation on
CISCO ASR 9000.
