Эмуляция Cisco IOS с помощью Cisco IOU. Доброго времени.
Когда речь заходит о том как эмулировать Cisco IOS все сразу в голове прокручивают : dynamips, dynagen или gns3 в конце концов, если хочется все в комплекте, да еще и с GUI Front end. Не так давно я писал о том, что Cisco с 17 января, в лабораторную CCIE RS в секцию TroubleShooting добавила Layer 2, используя виртуальную эмуляцию на основе L2IOU.
Я раньше не знал, что у Cisco есть свой эмулятор, начал искать информацию. Оказалось что некоторым успешно удалось у себя запустить все это дело, причем все работает неплохо, и что самое главное не ест столько процессорного времени как dynamips. В общем меня это заинтересовало и я решил попробовать. Во-первых, нужно найти IOU, ссылку здесь прямую выкладывать не буду, но кто хочет тот найдет в гугле без проблем В моем случае файл называется так: i86bi_linux-ipbase-ms Если мы его попробуем запустить, то получим следующее: . . . [license] ubuntu = 1010101010101010; где, 1010101010101010 это некие числа, любые, 16 штук . До скорых встреч.

EtherChannel Between a Cisco Catalyst Switch That Runs Cisco IOS and a Workstation or Server Configuration Example. Introduction This configuration example describes how to establish EtherChannel between a Cisco Catalyst Switch that runs Cisco IOS software and a workstation or server.
For Cisco Catalyst switches that run the Catalyst OS, refer to Configuring EtherChannel Between a Catalyst Switch Running CatOS and a Workstation or Server. EtherChannel allows multiple physical Ethernet links to combine into one logical channel, which allows the links in the channel to share traffic load, as well as redundancy in the event that one or more links in the channel fail. You can use EtherChannel to interconnect LAN switches, routers, servers, and clients via unshielded twisted pair (UTP) wiring or single-mode and multimode fiber. This document refers to Fast EtherChannel, Gigabit EtherChannel, Port Channel, Channel Group, and Port Group with a single term, EtherChannel.
This document covers the configuration of Layer 2 EtherChannel between a Catalyst switch and a server. Prerequisites Requirements Components Used.
All Voice and Unified Communications Product. InterVLAN Routing on Layer 3 Switches. How To Configure InterVLAN Routing on Layer 3 Switches. Introduction This document provides the configuration and troubleshooting steps applicable to the creation of Layer 3 interfaces.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) ). Note: This document uses a Catalyst 3550 as an example. Prerequisites Requirements Catalyst switch models 3560, 3750, Catalyst 4500/4000 Series with Sup II+ or later, or Catalyst 6500/6000 Series that run Cisco IOS system software support basic InterVLAN routing features in all their supported software versions.
InterVLAN routing on the Catalyst 3550 has certain software requirements in order to support interVLAN routing on the switch. Components Used The information in this document was created from the devices in a specific lab environment. Task.
