The Cisco EHWIC-D-8ESG is an 8-port 10/100/1000 Mbps managed Ethernet switch interface card for ISR 1900, 2900 and 3900 routers, delivering wire-speed Layer 2 switching and advanced QoS.
The EHWIC-D-8ESG is compatible with the Cisco ISR 1900, 2900 and 3900 series routers, plugging directly into any available Enhanced High-Speed WAN Interface Card slot.
Each of the eight RJ-45 ports auto-senses 10/100/1000 Mbps at wire speed, providing up to 16 Gbps of full-duplex internal switching capacity.
Yes. The EHWIC-D-8ESG supports IEEE 802.1Q VLAN tagging, port-based VLANs and dynamic VLAN assignment via GVRP for flexible network segmentation.
Power down your ISR, slide the EHWIC-D-8ESG into an empty EHWIC slot, secure the card with the captive screw, then power up and configure via Cisco IOS.
The card offers wire-speed bridging, IEEE 802.1D Rapid Spanning Tree, 802.1w/PVST+, port security, storm control and link aggregation (LACP).
Yes. It provides hardware-based classification, marking and policing, eight priority queues and hierarchical QoS policies for traffic prioritization.
You manage the switch ports through the Cisco IOS CLI or Cisco Configuration Professional via the built-in RJ-45 management port or console port.
No. The EHWIC-D-8ESG does not support Power over Ethernet and requires external PDUs or midspan injectors for PoE devices.
It includes access control lists (ACLs), port security with MAC address limiting, DHCP snooping and Dynamic ARP Inspection for enhanced edge security.
No. Each ISR chassis supports a maximum of two EHWICs, but you cannot stack cards—each functions independently in its slot.
The EHWIC-D-8ESG draws under 5 W and conforms to Cisco ISR thermal profiles; no additional cooling or power supplies are required.
Yes. It fully supports IPv6 traffic forwarding including multicast and QoS policies under Cisco IOS on the host router.
Cisco provides a limited lifetime warranty on the EHWIC-D-8ESG when purchased through a Cisco authorized reseller, with optional SMARTnet service for 24/7 support.
You update firmware by installing the latest Cisco IOS image on your ISR; the EHWIC automatically inherits updated features and bug fixes.
