4GE-2S (4-Port 1000BASE-SFP-L2 Ethernet Interface Card)
Card Overview
The 4GE-2S often applies to medium-sized enterprises and provides large-capacity gigabit Ethernet access. It provides four GE optical interfaces and can connect to optical interface switches.
A 4GE-2S card can be installed in a WSIC slot of a router.
Figure 7-42 shows the appearance of a 4GE-2S card.
Version Mapping
Table 7-111 lists the device models and software versions supporting the 4GE-2S.

Device Model |
|---|---|
4GE-2S NOTE:
This card is supported in V200R003C00 and later versions. When this card is used on a router, the minimum bandwidth and maximum bandwidth supported by the card are both 1 Gbit/s, due to the backplane bandwidth restriction. |
AR1200 series (All models in this series except the AR1220E, AR1220EV, AR1220EVW, AR1220-8GE, and AR1220C ) AR2204 AR2204E AR2204E-D AR2220 AR2220L-AC AR2220L-DC AR2220E AR2240 AR2240C AR3200 series |
Functions and Features
Table 7-112 describes the functions and features of a 4GE-2S card.
Function and Feature |
Description |
|---|---|
Four GE optical interfaces |
Provide up to 1000 Mbit/s line-rate switching. |
Duplex mode |
Supports the half duplex mode and full duplex modes. The full duplex mode is more commonly used. |
VLAN |
Supports a maximum of 128 VLANs. NOTE:
Because the 4GE-2S card is special, you need to run the set vlan-range command to configure the VLAN combination that is allowed to be created. This function takes effect only after the card is restarted. |
Voice VLAN |
Allows voice data flows to be transmitted preferentially, ensuring high quality voice services. |
The interfaces do not support the automatic mode. |
|
VLANIF |
Supports VLANIF interface configuration to increase the number of Layer 3 interfaces. |
Layer 2 features |
Support MAC, STP, RSTP, MSTP, and LLDP. |
