These low-density Gigabit Ethernet switches offer small to medium-sized businesses and enterprise branch offices a combination of switching and 4 integrated into a single device Figure 1.
Integration of these switches with Cisco IOS-XE Software allows network administrators to manage a single device using Cisco 4 tools or the router command-line interface CLI for LAN and WAN management needs.
This approach reduces network complexity, lowers maintenance contract costs, and lessens 4 training needs.
It also 4 software qualification efforts and delivers a consistent user experience at branch offices.
Additionally, these low-density Gigabit Ethernet switching modules enable Cisco's industry-leading power initiatives, including per-port Power over Ethernet PoE and Power over Ethernet Plus PoE+ power 4, which enhances the ability of узнать больше branch office to scale to higher performance requirements and still meet environmental initiatives for IT teams to operate a power-efficient network.
The ссылка на продолжение and 8-port Gigabit Ethernet LAN Switch NIMs provide line-rate Layer 2 switching across onboard Gigabit Ethernet ports.
The NIMs furthermore enable direct module-to-module communication through the use of the multigigabit fabric MGF.
From a single platform with an integrated switch, you can connect IP phones, wireless access points, and IP-based video cameras to your network and power them 4 IEEE 802.
With the optional integration of Cisco Unified Communications Manager Express, the router can also provide call processing for the phones.
As users attempt network access, the NIMs can use IEEE 802.
Features and Benefits The Gigabit Ethernet LAN Switch NIMs provide increased performance levels, https://csgoup.ru/100/plenka-dlya-laminirovaniya-paketnaya-lf-85-h-120-mm-60-mkm-glyantsevaya-100-sht.html per-port security, and ease of configuration.
In addition, with intermodule cascading capabilities, they allow for port expandability over time.
Table 1 lists some important business benefits of deploying an integrated switching solution.
Power over Ethernet Читать PoE has been employed for more than a decade, the technology is still evolving.
New and innovative applications continue to raise power requirements.
The Cisco Gigabit Ethernet LAN Switch NIMs take advantage of the increased power capabilities of the Cisco 4000 Увидеть больше ISRs.
Table 9 provides information about total PoE 802.
Depending on the ISR platform type, total available power offered to PoE devices by the NIMs ranges from 120W to 500W.
Multigigabit Fabric The LAN switch NIMs have a gigabit connection to the MGF and transparently integrate into the system.
Layer 2 switching of packets is thus done at the full Gigabit Ethernet line rate, either local to each LAN switch NIM or when transferring the MGF with multiple MGF-enabled modules installed in the system; module-to-module MGF traffic throughput is limited to 1 Gbps.
Direct Module-to-Module Connection Without Involving CPU Applications Small and Medium-Sized Branch Offices The Cisco Gigabit Ethernet LAN Switch NIMs in a small to medium-sized enterprise branch-office data deployment scenario provide the flexibility of integrated routing and switching functions in one device.
This scenario allows the deployment of high-speed connections between individual network resources such as client desktops, servers, IP phones, wireless access points, and video devices from a 4 device and at the same time allows for WAN connectivity at Layer 3 through the router.
When deployed in 4 unified communications environment, the 4- or 8-port NIMs transparently interoperate with analog or продолжение здесь time-division multiplexing TDM voice gateway modules and Cisco Unified Communications Manager Express IP Telephony, Cisco Survivable Remote Site Telephony SRSTor Cisco Unified Border Element solutions.
In addition, the NIMs support separate VLAN configuration for IP phones.
The auxiliary VLAN feature allows network administrators to segment phones into separate logical networks, even though the data and voice infrastructures are physically the same.
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 4 the посетить страницу NIMs, and Table 4 lists the maximum number of VLANs supported per platform.
The NIMs are capable of cascading on all Cisco 4000 Series ISRs using the internal MGF.
The router CPU is not involved in this operation.
Strict priority is enforced by default.
The routers support SDWRR with configurable weight on each queue.
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.
Support is provided for both IEEE 802.

The Cisco Gigabit Ethernet LAN Switch NIMs enable a high level of performance as well as POE+ capabilities.
Other benefits are advanced Layer 2 switching features for data and IP communications, easy expandability, and simplified branch-office router management.
