Introduction
The
Cisco 16- and 36-port 10/100 EtherSwitch modules
for Cisco 2600, 2800, 3600, 3700, 3800 series
routers offer branch office customers the
option to integrate switching and routing
in one platform. Combining robust Layer 3
flexible WAN routing with low-density line-rate
Layer 2 switching, the EtherSwitch modules
provide straightforward configuration, easy
deployment and integrated management in a
single platform.
The
EtherSwitch options include a 16-port network
module (NM) and a 36-port high density service
module (HDSM) version. The 36-port HDSM utilizes
the extra capacity from the wider interface
form factor available only on the Cisco 2851,
3660, 3700, and 3800 series routers to increase
the maximum possible port densities. The 16-port
EtherSwitch NM is available for the Cisco
2600, 2800, 3600, 3700, and 3800 series routers.
The
combination of Cisco 2600, 2800, 3600, 3700,
and 3800 Series routers and the EtherSwitch
modules utilize the powerful features available
in both Cisco IOS® software and Catalyst
switching. The EtherSwitch module hardware
supports 802.1p Layer 2 prioritization, while
Cisco IOS software supports Layer 3 DiffServ
and Class of Service (CoS) markings for critical
business data. Coupling Layer 2/3 prioritization
techniques, with the QoS for the WAN, this
integrated routing and switching combination
ensures low latency for critical business
applications. The Cisco EtherSwitch modules
includes 10/100 switched Ethernet ports with
options for Cisco pre-standard power over
ethernet and Gigabit Ethernet. Features such
as port autosensing, QoS and VLAN support
from 802.1p and 802.1Q standards, and 802.1D
Spanning Tree protocols are standard on the
EtherSwitch modules.
The
Cisco 16- and 36-port EtherSwitch modules
are available with optional Cisco pre-standard
Power over Ethernet and Gigabit Ethernet support.
EtherSwitch bundles are available with these
options pre-installed for easy ordering. The
integrated power over ethenet supports Cisco
IP phones and Cisco Aironet wireless access
points. An external power supply is needed
for this feature in Cisco 2600/3600 platforms.
An Internal power supply option is available
on the Cisco 2800*, 3700, and 3800* Series.
For 802.3af power over Ethernet support one
of the newer EtherSwitch Service Modules (NME-16ES-1G-P,
NME-23ES-1G-P, or NME-XD-48ES-2S-P) or one
of the EtherSwitch HWICs (HWIC-4ESW-POE or
HWIC-D-9ESW-POE) are recommended.

|
Delivers
up to 200 Mbps of bandwidth (full duplex)
Layer 2; forwards and filters backflow
at full wire speed on each port
|
|
Autosensing
on Each Port
|
Detects
