Possibility of creating port-channel interface with EHWIC-4ESG

Hey everyone

is it possible to put EHWIC-4ESG ports in a port-channel interface in ISR 2911 ?

it is a 4-port single-wide Gb Ethernet switch so i think it should be possible.

Thanks for your time.

I am trying to create a port channel on the HWIC--4ESW, there is no option on the FastEthernet interfaces on the module to join a channel group. So it is not possible to create port channels on these modules. You can create a port channel with the three on-board GigabitEthernet interaces only.

@gpauwen, thank you for responce. for now i find related documents about the Cisco® Gigabit Ethernet LAN Switch Network Interface Modules.

Features and Benefits

Table 2 provides an overview of the architecture, features, and benefits of the 4-port and 8-port Cisco Gigabit Ethernet LAN Switch NIMs, Table 3 lists other features of the new NIMs, and Table 4 lists the maximum number of VLANs supported per platform.

Table 2.       Architecture, Features, and Benefits

Feature

Benefit

4 or 8 10/100/1000BASE-TX ports

  The switches offer line-rate forwarding for Layer 2 traffic on each port.

Autosensing, autonegotiation, and Automatic Media-Dependent Interface Crossed Over (Auto-MDIX)

  Autosensing allows the switch to detect the speed of the attached device and automatically configure the port for 10-, 100-, or 1000-Mbps operation.
  Autonegotiation allows the switch to automatically select half- or full-duplex transmission mode to optimize bandwidth on all the ports of the NIM.
  Auto-MDIX allows the switch to automatically detect cable type (straight-through vs. crossover) between an attached device and the switch port.

Integrated switching

  Integrated switching provides fewer points of management for remote and small branch offices.

Intrachassis stacking or cascading

  Grouping LAN switch NIMs together is called cascading. The NIMs are capable of cascading on all Cisco 4000 Series ISRs using the internal MGF.
  Cascading of multiple LAN switch NIMs over the MGF allows multiple NIMs to behave as a single switch.
  Layer 2 switching of packets can be internal to each LAN switch NIM, or they can go through the MGF when multiple LAN switch NIMs in the system are acting as a unified switch. The router CPU is not involved in this operation.

IEEE 802.1P QoS (Traffic Prioritization)

  This feature supports QoS based on the IEEE 802.1P class of service (CoS) and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port basis.
  Each port has four QoS queues. Strict priority is enforced by default. The routers support SDWRR with configurable weight on each queue.

802.1Q Trunking

  This feature provides an industry wide VLAN tagging standard, allowing for trunks also to be set up to third-party devices.

802.1D Spanning Tree Protocol

  This industry-standard link layer network protocol helps ensure a loop-free topology between Layer 2 devices regardless of vendor. IEEE 802.1D Spanning Tree Protocol is turned off by default.

Voice VLAN (VVLAN)

  VVLANs enable Cisco IP phones to place voice and data in their own separate VLANs. The NIM switch port is manually configured as a trunk port to support voice and data VLANs on the same port. The switch then uses Cisco Discovery Protocol to dynamically configure the Cisco IP phones.

IEEE 802.1X authentication

  Support for 802.1X port-based authentication, single/multiple host mode, guest VLAN, MAC Authentication Bypass (MAB), restricted VLAN, critical VLAN, and dynamic VLAN.

PoE+ (option)

  Cisco Gigabit Ethernet technology with the appropriate PoE+ module and internal power supply can power Cisco IP phones and wireless access points. Support is provided for both IEEE 802.3af (PoE) and IEEE802.3at (POE+).

IP Multicast management support

  The routers provide Internet Group Management Protocol (IGMP) Snooping in hardware for management support.

SNMP management

  SNMP allows management of the MIB through a MIB browser.

Cisco IOS® Software CLI

  This feature provides configuration through the Cisco IOS Software CLI and provides a common user interface for all the router functions.

CiscoWorks support

  CiscoWorks network management software enables management on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs.
  SNMPv1, v2, and v3 (noncryptographic) and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management.
  Cisco Discovery Protocol Versions 1 and 2 enable a CiscoWorks network management station to automatically discover the switch in a network topology.
  Support is provided by the CiscoWorks LAN Management Solution.

Cisco Discovery Protocol Versions 1 and 2

  This protocol enables a CiscoWorks network management station to automatically discover the switch in a network topology.

Cisco VLAN Trunking Protocol
(VTP; client, server, and transparent modes)

  Cisco VTP supports dynamic VLAN configuration across Cisco switches.

Cisco Configuration Professional -based configuration and device management

  This feature simplifies initial configuration of a switch through a web-based GUI, eliminating the need for more complex terminal emulation programs and CLI knowledge.
  Cisco Discovery Protocol reduces the cost of deployment by helping less-skilled personnel set up switches quickly and simply.

Status-indicator LEDs

  Two LEDs per port provide visual indication of the switch-port status and PoE status.

Hello Manwe,
