4507 SSO mode Sup7L-E 10GbE interfaces

[Brendan Marmont]

Hi,

What is the case with redundant Sup engine 10GbE interfaces. We can only get one in active state, the other interface stays inactive? Can we have all four interfaces active sharing the backplane?

Hi Brendan,

The Supervisor Engine 7L-E has four uplink ports. Ports 1 and 2 support either 10GBASE SFP+ transceivers or 1000BASE SFP transceivers. Ports 3 and 4 support only 1000BASE SFP transceivers. There are restrictions on the use of the uplink ports in both single supervisor engine and redundant supervisor engine configurations and both 10-G and 1-G operation.

Refer the below Table for a matrix of uplink port permissible transceiver configurations and transceiver restrictions.

Table 3 Uplink Port SFP+ and SFP Transceiver Configurations

Port 1	Port 2	Port 3	Port 4	Comments
Single Supervisor Engine Configuration. 10-Gigabit Operation Selected Through CLI
SFP+	SFP+	Not usable	Not usable	Maximum bandwidth is 20 Gbps. SFP+ transceivers are installed in ports 1 and 2. Port 3 and port 4 are not usable.
SFP+	SFP	Not usable	Not usable	Maximum bandwidth is 11 Gbps. With SFP and SFP+ transceivers installed in ports 1 and 2, port 3 and port 4 are not usable. 10-Gigabit operation selected through CLI.
SFP	SFP+	Not usable	Not usable	Maximum bandwidth is 11 Gbps. With SFP and SFP+ transceivers installed in ports 1 and 2, port 3 and port 4 are not usable. 10-Gigabit operation selected through CLI.
SFP	SFP	Not usable	Not usable	Maximum bandwidth is 2 Gbps. With SFP transceivers installed in ports 1 and 2, port 3 and port 4 are not usable. 10-Gigabit operation selected through CLI.
Single Supervisor Engine Configuration. 1-Gigabit Operation Selected Through CLI
SFP	SFP	SFP	SFP	Maximum bandwidth is 4 Gbps. Any combination of SFP transceiver type can be used. SFP+ transceivers can not be used in this configuration.
Redundant Supervisor Engine Configurations. 10-Gigabit Operation Selected Through CLI
AS1—SFP+ SS2—SFP+	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	Maximum bandwidth is 20 Gbps. If you plan to populate two uplink ports with SFP+ transceivers, you must install one SFP+ transceiver in the active supervisor engine (port 1) and one SFP+ transceiver in the standby supervisor engine (port 1).
AS—SFP+ SS—SFP	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	Maximum bandwidth is 11 Gbps. If you plan to populate only two uplink ports with one SFP+ transceiver and one SFP transceiver, you can install one SFP+ transceiver in the active supervisor engine (port 1) and one SFP transceiver in the standby supervisor engine (port 1).
AS—SFP SS—SFP+	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	AS—Not usable SS—Not usable	Maximum bandwidth is 11 Gbps. If you plan to populate only two uplink ports with one SFP+ transceiver and one SFP transceiver, you can install one SFP transceiver in the active supervisor engine (port 1) and one SFP+ transceiver in the standby supervisor engine (port 1).

AS = Active supervisor engine.

SS = Standby supervisor engine.
