Understanding Cisco Nexus 2000 Series Fabric Extenders

Cisco Nexus 2248PQ Fabric Extender

Cisco Nexus 2248PQ Fabric Extender

Cisco Nexus 2000 Series Fabric Extenders (FEX) behave and can be considered as remote line cards for Cisco Nexus switches. The fabric extender acts as an extension to the parent Cisco Nexus switch fabric; the fabric extender and the parent Cisco Nexus switch together form a distributed modular system. With this architecture, the fabric extender typically is at top-of-rack (ToR) with the parent Cisco Nexus switch at end-of-row (EoR). (more…)

802.1Q Trunking Between Cisco and Dell Force10 Switches

Monday, July 2nd, 2012

VOIP PhonesIn this lab I use a Dell Force10 S25P switch [FTOS 8.4.2.6] and a Cisco C3750 switch [IOS 12.2(25)SEE3] to demonstrate 802.1Q trunking. (more…)

Creating a LAG between an ESXi vSwitch and a Physical Switch

Sunday, October 30th, 2011

In this lab I am going to create a LAG (Link Aggregation Group) between an ESXi vSwitch and a physical switch. You can use Cisco, Force10 Dell, Juniper, or any other manufacturer for the physical switch. Depending on the switch you use, the commands may vary on the physical switch for creating a LAG (referred to as port-channel by Force10 Dell and etherchannel by Cisco). I will not get into details of creating a LAG; please reference my earlier posts Creating a Link Aggregation Group (LAG) in FTOS and Setting up Cisco EtherChannels – Static, PAgP, and LACP for this information.

Setting up Cisco EtherChannels – Static, PAgP, and LACP

Thursday, June 2nd, 2011

In this lab I used a Cisco Catalyst WS-C3750G-24TS switch [IOS 12.2(25)SEE3] and a Cisco Catalyst WS-C3560G-24TS switch [IOS 12.2(40)SE]. I also physically connected GigabitEthernet 1/0/17 on the Catalyst 3750G to GigabitEthernet 0/17 on the Catalyst 3560G; I did the same for GigabitEthernet 1/0/18 and GigabitEthernet 0/18 respectively. At this point I have two GigabitEthernet connections between the switches. (more…)

Creating a Link Aggregation Group (LAG) in FTOS

Monday, May 9th, 2011

This lab demonstrates how to create a Link Aggregation Group (LAG) in FTOS on Force10 switches. A LAG in Force10′s FTOS is called a port channel and in Cisco’s IOS is called an EtherChannel. As described by IEEE 802.3ad, LAG is a mechanism for combining the bandwidth of multiple physical ports in a switch into one logical link. Therefore, a port channel can be treated as an individual port and can be configured as such (ex: can be set as Layer 2 or Layer 3, can be part of a VLAN, etc.). (more…)
