Ex8200-2Xs-40T Line Card - Juniper EX8208 Hardware Manual

Table 42: Ports on the EX8200-2XS-40P Line Card (continued)
Port Number Port Type
44 and 45 SFP+
The ports are divided into two port groups:
The RJ-45 ports 0–19 and SFP ports 40 and 41 form one port group.
The RJ-45 ports 20–39 and SFP ports 42 and 43 form another port group.
The ports in each group share 10 gigabits of bandwidth. The SFP ports operate at 1 gigabit bandwidth.
Thus, you can transmit up to 8 gigabits of traffic through a port group when the SFP ports are active and
up to 10 gigabits when the SFP ports are not active, without packet drop. The oversubscription ratios of
different port groups can differ from one another; the ratios depend on the amount of traffic being
transmitted through a port group.
For more information about using these ports:
To understand how traffic is handled by oversubscribed ports, see Understanding CoS Queues on EX8200
