IEEE Launches Study Group to Explore 400Gb/s Ethernet.

Posted by Peter Kurdziel on April 4, 2013

IEEE, the world’s largest professional organization advancing technology for humanity, today announced the launch of an IEEE 802.3 standard for Ethernet study group to explore development of a 400Gb/s Ethernet standard to efficiently support ever-increasing, exponential network bandwidth growth.

“Traffic is growing everywhere – more Internet users, more ways to access the Internet more quickly, higher-bandwidth content, new applications enabled, etc. – and it is critical that we move now to create a plan for the Ethernet ecosystem to evolve beyond today’s capabilities, in order to accommodate the burgeoning bandwidth tsunami,” said John D’Ambrosia, chair of the new IEEE 802.3 400 Gb/s Ethernet study group and chief Ethernet evangelist at Dell.

Configuring the Cisco Nexus 2000 Series Fabric Extender

Posted by Peter Kurdziel on March 12, 2013

Configuring a FEX with a Layer 3 Host Interface

This example shows how to configure a Fabric Extender with a Layer 3 host interface (at the interface level, subinterface level, port channel level, and port channel subinterface level):

Layer 3 Configuration Layer 3 Subinterface Configuration 
config t
interface ethernet 101/1/1
no switchport
ip address 192.0.1.1/24
Mtu 9000
no shutdown
 
config t
interface ethernet 101/1/1.12
ip address 192.0.2.1/24
encapsulation dot1Q 12
mtu 850
no shutdown

Layer 3 Host Interface Port Channel Configuration Layer 3 Host Interface Port Channel Subinterface Configuration 
config t
interface ethernet 101/1/1-2
no switchport
channel-group 12
no shutdown

interface port-channel 12
ip address 192.0.3.1/24
mtu 2000
no shutdown
 
config t
interface ethernet 101/1/1-2
no switchport
channel-group 12
no shutdown

interface port-channel 12.14
ip address 192.0.4.1/24
encapsulation dot1Q 14
mtu 1700
no shutdown

Note

The VLAN used in the Layer 3 host interface (HIF) or host interface port channel (HIFPC) subinterface has only local significance to its parent interface. The same VLAN ID can be reused between Layer 3 subinterfaces in the same switch or VDC.

Configuring a Host Interface in a vPC Topology Connected to Two FEXs

This example shows how to configure a host vPC with a FEX (host vPC attached to two different FEXs):

Switch 1 Configuration Switch 2 Configuration 
config t
feature lacp
int e101/1/1-2
channel-group 12 mode active
no shutdown

Int port-channel10
switchport
  switchport mode trunk
  switchport trunk allowed vlan 1-20
vpc 10
 
config t
feature lacp
int e101/1/1-2
channel-group 12 mode active
no shutdown

Int port-channel10
switchport
  switchport mode trunk
  switchport trunk allowed vlan 1-20
vpc 10

Configuring a FEX in Active-Active Mode

This example shows how to configure a FEX in active-active mode:

Switch 1 Configuration Switch 2 Configuration 
int eth 1/1
channel-group 1
int po1
switchport
switchport mode fex-fabric
fex associate 101
vpc 10
 
int eth 2/2
channel-group 2
int po2
switchport
switchport mode fex-fabric
fex associate 101
vpc 10

Note
  • The chassis number (fex-id) for both switches must be the same.
  • Configuring FEX-AA across two VDCs on the same chassis is not supported.
  • FEX-AA does not support Layer 3 interfaces.

Dual-homing of a Server to a FEX with FabricPath

To configure FabricPath interfaces for two Cisco Nexus 7000 Series switches that are connected with FabricPath, perform the following tasks on each switch:

  • Enable FabricPath on each switch.
  • Configure the interfaces that you want to designate as FabricPath interfaces.
  • Set the STP priority device to 8192 on all FabricPath Layer 2 gateway devices.
  • (Optional) Set the STP domain ID for each of the separate STP domains that are connected to the FabricPath network.
  • (Optional) Configure a FEX switch ID.

To configure FabricPath interfaces, follow these steps:

  1. (Optional) Enable FabricPath on each switch. 
    switch# config terminal
switch(config)# feature fabricpath
switch(config-lldp)# exit
switch(config)#
  2. After you enable FabricPath on the switch, configure the specified interface as FabricPath interfaces. 
    switch(config)# interface ethernet 1/2
switch(config-if)# switchport mode fabricpath 
switch(config-if)# exit
switch(config)#
  3. Configure the STP priority for all Rapid PVST+ VLANs as 8192. 
    switch# config terminal 
switch(config)# spanning-tree vlan 11-20 priority 8192
switch(config)#
  4. Configure the STP priority for all MST instances as 8192. 
    switch# config terminal 
switch(config)# spanning-tree mst 1-5 priority 8192
switch(config)#
  5. (Optional) Configure the STP domain ID on each FabricPath Layer 2 gateway switch attached to the FabricPath network. 
    switch# config terminal 
switch(config)# spanning-tree domain 5
switch(config)
  6. (Optional) Configure the FEX switch ID.

    Note

    See the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide for information on configuring FEX.

    Note

    FEX VPC+ configurations are supported only on F2 modules.

    If you are setting up an initial FEX VPC+ configuration on an F Series module, follow these steps:

    1. In the VPC domain configuration mode, enable partial DF mode with the fabricpath multicast load-balance command.
    2. If disabled, enable TRILL style mac-address learning with the mac address-table core-port-learning command.
    3. In the VPC domain configuration mode, configure the emulated switch ID with the fabricpath switchid switchid#command.
    4. On each of the VPC/VPC+ peer link interfaces in interface configuration mode, enter the switchport mode fabricpath command.
    5. On each VPC/VPC+ peer link port channel, enter the VPC peer-link command.
    6. Configure the VPC ID with the vpc vpcid command.

    If you are changing an existing FEX VPC configuration to a FEX VPC+ configuration on an F Series module, follow these steps:

    1. In the VPC domain configuration mode, enable partial DF mode with the fabricpath multicast load-balance command.
    2. If disabled, enable trill style mac-address learning with the mac address-table core-port-learning command.
    3. In the VPC domain configuration mode, configure the emulated switch ID with the fabricpath switchid switchid# command.
  7. Copy the configuration. 
    switch(config)# copy running-config startup-config
switch(config)#

Verifying the Configuration

 

This section describes how to display the configuration of the Fabric Extender and verify the chassis hardware status.

Verifying the Fabric Extender Configuration

 

To display configuration information about the defined interfaces on a Fabric Extender, perform one of the following tasks:

Command or Action Purpose
show fex [FEX-number] [detail] Displays information about a specific Fabric Extender or all attached units.
show interface type number fex-intf Displays the Fabric Extender ports that are pinned to a specific switch interface.
show interface fex-fabric Displays the switch interfaces that have detected a Fabric Extender uplink.
show interface ethernet number transceiver [fex-fabric] Displays the SFP+ transceiver and diagnostic optical monitoring (DOM) information for the Fabric Extenderuplinks.
show feature-set Displays the status of the feature sets on the device.

Nexus Q-in-Q and Layer 2 Protocol Tunneling config and verification

Posted by Peter Kurdziel on March 12, 2013

Service provider switch configured to process Q-in-Q for traffic coming in on Ethernet 7/1. A Layer 2 protocol tunnel is enabled for STP BPDUs. The customer is allocated VLAN 10 (outer VLAN tag).

switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# vlan 10
switch(config-vlan)# no shutdown
switch(config-vlan)# no ip igmp snooping
switch(config-vlan)# exit
switch(config)# interface ethernet 7/1
switch(config-if)# switchport
switch(config-if)# switchport mode dot1q-tunnel
switch(config-if)# switchport access vlan 10
switch(config-if)# spanning-tree port type edge
switch(config-if)# l2protocol tunnel stp
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# exit
switch#

Verifying the Q-in-Q Configuration

clear l2protocol tunnel counters [interface if-range] = Clears all the statistics counters. If no interfaces are specified, the Layer 2 protocol tunnel statistics are cleared for all interfaces.

show dot1q-tunnel [interface if-range] = Displays a range of interfaces or all interfaces that are in dot1q-tunnel mode.

show l2protocol tunnel [interface if-range | vlan vlan-id] = Displays Layer 2 protocol tunnel information for a range of interfaces, for all dot1q-tunnel interfaces that are part of a specified VLAN or all interfaces.

show l2protocol tunnel summary = Displays a summary of all ports that have Layer 2 protocol tunnel configurations.

show running-config l2pt = Displays the current Layer 2 protocol tunnel running configuration.
