Restrictions for Instant Access

  • The IA parent must operate in VSS mode.

Note • You can enable VSS mode on a single chassis to support IA clients.
• The VSS Quad-Sup SSO (VS4O) feature is supported with IA clients from Release 15.1(2)SY2.


  • The IA parent-client connection is supported on links between WS-X6904-40G-2T switching module 10GE ports and Catalyst 6800ia access switch 10GE ports.

You can use up to 6 IA client 10GE ports in the IA parent-client link. See this document for information about WS-X6904-40G-2T switching module port configuration:

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-696669.html

IA client 10-Gigabit Ethernet ports require no configuration.

UDLD, LLDP, and CDP are not supported on the A parent-client link.

Instant Access does not use STP on the IA parent-client connection.

  • IA client maximum values:

 

Value Description:
Maximum Value

Maximum IA client ports

1,008 ports across across 21 Catalyst 6800ia access switches

Maximum IA client stacks

12 (defined by IA client FEX number 1–12 range.)

Maximum Catalyst 6800ia access switches per IA client stack

3

  • An IA client stack acts as single switch unit.
  • Instant access only supports connection with stacking cables to form a stack.
  • With an IA client that has multiple Catalyst 6800ia access switches, the switches in the stack assign incrementing switch numbers to themselves (automatic stacking capability).
  • If you add Catalyst 6800ia access switches to a configured IA client, the additional switches assign incrementing switch numbers to themselves.
  • The IA client configuration does not persist if the access switch number changes.

Maximum number of VLANs per IA client stack

1,024

  • IA client ports do not support these features:

Configuring EtherChannels with combination of FEX Ports from different FEX-IDs or combination of FEX ports with IA parent switch linecard ports is not supported.

  • To use an IA client port as a SPAN destination, add the IA client port VLAN to the SPAN allowed VLAN list with the switchport trunk allowed vlan command.
  • When FEX IA parent-client link portchannel is configured as SPAN source in Tx direction or both directions, the SPAN destination should not be on the same FEX. This is applicable for both stacked and standalone FEX.
  • To enable formation of ISIS adjacencies on IA client ports, configure an explicit connectionless network service (CLNS) MTU size on the IA client and peer ports. This example shows how to configure the default MTU size on an IA client port:
Router# configure terminal
Router(config)# interface interface Gig118/1/0/1
Router(config-if)# ip router isis
Router(config-if)# clns mtu 1497

Information About Instant Access

The Instant Access (IA) feature supports multiple Catalyst 6800ia access switches that function as clients of the IA parent switch. The IA parent and client switches form a single extended switch with a single management domain, managed by the IA parent.

The IA parent uses the Satellite Discovery Protocol (SDP) and the Satellite Registration Protocol (SRP) to automatically discover IA clients when they connect and monitor the IA client-parent link. The IA parent upgrades the IA client software image if it is not the same as the parent.

The IA parent features are applied to IA client traffic. The IA clients do not perform any local packet forwarding. All traffic originating from IA client ports are sent to the IA parent, which makes all the switching and forwarding decisions.

These online diagnostic tests support Instant Access clients:

Default Settings for Instant Access

None.

How to Configure Instant Access

Configure Instant Access Staggered Initialization Mode

Instant Access staggered initialization mode avoids any excessively high CPU utilization that might occur if multiple IA client attempted to initialize simultaneously. To configure Instant Access staggered initialization mode, perform this task:

 

Command
Purpose

Router(config)# fex stagger delay_value

Configures Instant Access staggered initialization mode. The delay_value can be 0 through 500.

Note The recommended delay_value is 120.

This example shows how to configure Instant Access staggered mode:

Router# configure terminal
Router(config)# fex stagger 120

Enable IA Client Preprovisioning

To allow IA client port configuration before the IA client is connected, perform this task:

 

Command
Purpose

Router# module provision create fex fex_number type { C6800IA-48FPD | C6800IA-48TD } [ slot switch_number ]

Enables IA client port configuration before the IA client is connected. Enter the slot switch_number keyword and argument to enable configuration of a specific IA client stack member or an additional stack member before it is added to the IA client stack.

Configure Instant Access Port-Channel Interfaces

To create a port channel interface to support IA clients, perform this task:

 

Command
Purpose

Step 1

Router(config)# interface port-channel group_number

Creates the port channel interface. The group_number can be 1 through 256, up to a maximum of 128 port-channel interfaces (12 port-channel interfaces can be used to support IA clients).

Note If desired, you can configure the group_number to match the IA client FEX number.

Step 2

Router(config-if)# switchport

Configures the port channel interface for Layer 2 switching.

Step 3

Router(config-if)# switchport mode fex-fabric

Configures the port channel interface to support IA clients.

Step 4

Router(config-if)# fex associate fex_number

Configures the IA client FEX number.

  • The valid value range is 101–199.
  • Maximum of 12 IA client FEX numbers.

This example shows how to create port channel interface 1 and configure it to support IA FEX number 118:

Router# configure terminal
Router(config)# interface port-channel 118
Router(config-if)# switchport
Router(config-if)# switchport mode fex-fabric
Router(config-if)# fex associate 118

Configure Instant Access Channel Groups

To configure channel groups to support IA clients, perform this task for the 10 Gigabit Ethernet LAN ports that connect to IA clients:

 

Command
Purpose

Step 1

Router(config)# interface range first_10ge_port, last_10ge_port

Selects the ports to configure.

Step 2

Router(config-if)# no ip address

Ensures that there is no IP address assigned to ports.

Step 3

Router(config-if)# no channel-protocol

Ensures that there is no EtherChannel protocol configured on the ports.

Step 4

Router(config-if)# channel-group group_number mode on

Configures the LAN port in an IA Client port channel and configures the mode as on .


NoteMore links can be added to the channel group at any time.


This example shows how to configure 10 Gigabit Ethernet ports 1/2/5 and 2/2/5 into port channel 118 with mode on :

Router# configure terminal
Router(config)# interface range tengigabitethernet 1/2/5, 2/2/5
Router(config-if)# channel-group 118 mode on
Router(config-if)# end
 

This example shows how to verify the IA configuration when the IA client is connected:

Router# show fex 118 detail
FEX: 118 Description: FEX0118 state: online
FEX version: version_string
Extender Model: C6800IA-48TD, Extender Serial: serial_number
FCP ready: yes
Image Version Check: enforced
Fabric Portchannel Ports: 2
Fabric port for control traffic: Te1/2/5
Fabric interface state:
Po20 - Interface Up.
Te1/2/5 - Interface Up. state: bound
Te2/2/5 - Interface Up. state: bound

Identify IA Client Stack Modules by Serial Number

This example shows how to identify IA client stack modules by serial number:

Router# show interface fex
Fabric Fabric Port FEX FEX
FEX Port State Uplink Model Serial
---------------------------------------------------------------------
101 Te1/2/5 bound Te1/0/1 C6800IA-48FPD FHH1707P00S
101 Te1/2/13 bound Te2/0/1 C6800IA-48FPD FHH1707P00S
101 Te2/2/5 bound Te1/0/2 C6800IA-48FPD FHH1707P00S
101 Te2/2/13 bound Te2/0/2 C6800IA-48FPD FHH1707P00S
102 Te1/2/6 bound Te1/0/2 C6800IA-48TD FOC1709Z2V9
102 Te2/2/17 bound Te2/0/2 C6800IA-48TD FOC1709Z2V9

Identify IA Client Modules by Beacon LED

This example shows how to activate the beacon LED on IA client 118, module1:

Router# hw-module fex 118 module 1 led beacon

Configure IA Clients

The configuration for IA clients can be entered on the IA parent before or after the IA clients are connected. IA client 10-Gigabit Ethernet ports require no configuration. IA client Gigabit Ethernet ports use this format:

gigabitethernet / fex_number / access_switch_number /0/ port_number

fex_number —The IA client FEX number:

—Maximum of 12 IA FEX numbers.

—The valid value range is 101–199.

access_switch_number —The access switch number:

—The valid values are 1, 2, or 3.

—Multiple-switch stacks assign incrementing switch numbers to themselves.

—See the “Identify Connected IA Client Stack Modules” section.

The third interface parameter is always zero.

The port_number valid value range is 1–48.


Note • IA client configuration does not persist if the access switch number changes.


 

Display or Clear SDP and SRP Traffic

To display the counters that record the SDP packet traffic on IA client 118, enter the following command:

Router# show fex 118 protocol | incl SDP
130 SDP pkts sent
129 SDP pkts received
130 SDP pkts sent
129 SDP pkts received
 

NoteThe command displays a sent and received value for each link in the IA channel group.


To clear the protocol counters, enter the clear fex fex_number { sdp | srp } command.

Enter the IA Client Configuration Mode

To enter the IA client configuration mode, perform this task:

 

Command
Purpose

Router(config)# fex fex_number

Router(config-fex)#

Enters IA client configuration mode.

Note Sets the IA client description to FEX0fex_number.

Configure a Description

To configure a description for the IA client or for each module in the IA client stack, perform this task:

 

Command
Purpose

Router(config-fex)# [ module module_number ] description description_string

Configures a description for the IA FEX number or for a module in the IA client stack.

Configure the Custom Location Type Feature

You can configure the custom location type feature for the IA client in IA client configuration mode. See these publications for information about the location command:

http://www.cisco.com/en/US/docs/ios-xml/ios/cether/command/ce-cr-book.html
