1. LEDs indicating port activity are above the RJ-45 and SFP+ port. The up arrow on the left indicates the
top port; the down arrow on the right indicates the bottom port.
2. 48 ports — The VSP 7254XSQ has 48 SFP/SFP+ fiber ports. The VSP 7254XTQ has 48 RJ-45 copper
ports.
3. Six QSFP+ ports — The LEDs are below each port. There are four LEDs per port to support
channelization. The up arrows refer to the port above.
4. USB port
5. LEDs for system power (PWR), switch status (Status), redundant power supply (RPS), and fan modules
(Fan).
Interface indexes
The Simple Network Management Protocol (SNMP) uses interface indexes to identify ports, Virtual
Local Area Networks (VLAN), and Multilink Trunking (MLT).
Port interface index
To determine the interface index (IfIndex), you can calculate it, or use the CLI command given
below.
As a result of the channelization support for 40–gigabit ports, the ifIndex of each 40–gigabit port
increases by 4. The number is reserved for the 3 sub-ports when channelization is enabled.
If the first port is not a 40–gigabit port, the ifIndex of this port is (64 x slot number) +128 + (port
number -1).
If the first port is a 40–gigabit port, the ifIndex of the first port is (64 x slot number) +128, and
IfIndex of the next port is (64 x slot number) +128 + ((port number -1) *4).
The slot numbers are 1-2 for the VSP 7200 Series.
The slot numbers are 1-2 for the VSP 8200.
The slot numbers are 1-4 for VSP 8400.
To determine the port interface index through the ACLI, use the following command:
