2.1 Reference Diagrams

2.1.1Diagram 1 : Stackable Ethernet Routing Switch

Figure 1: Base setup - Stackable Ethernet Routing Switch Setup

The following are the details for the base configuration:

ERS-Stackable is a stackable Ethernet Routing Switches (ERS 2500, 4000, or 5000 series) setup as a Layer 2 switch connected to an SMLT Cluster

The SMLT Cluster requires that DHCP Relay be enabled with a DHCP Relay agent for both the voice and data VLANs

Overall, we will configure the following

o Create Voice VLAN 805 with port members 3 to 11, 23, and 24 o Create Data VLAN 1002 with port members 3 to 11, 23, and 24 o Create Management VLAN 201 with port members 23 and 24

oConfigure access ports 3 to 11 to allow untagged Data VLAN 1002 and tagged Voice VLAN 805

oConfigure core ports 23 and 24 using MLT 1 using VLAN tagging and with Spanning disabled

oUse all the recommended SMLT best practices

Details regarding various Avaya IP Phone DHCP and provisioning file parameters are listed in Appendix A

2.1.3Diagram 2 : Ethernet Routing Switch 8300

Figure 2: Base setup - Ethernet Routing Switch 8300 Setup

Overall, we will configure the following:

Create Voice VLAN 220 with port members 1/1 to 1/25

Create Data VLAN 61 with port members 1/1 to 1/25

Create Trunk VLAN 83 with port member 5/5

Enable DHCP relay for VLAN 220 and 61

Enable Spanning Tree Fast-Start on ports 1/1 to 1/25 and disable STP on port 5/5

Configure all voice ports, 1/1 to 1/25, with POE priority of high

Enable RIP on all VLANs

By default, the ERS 8300 passes both the DSCP and p-bit values as-is. The p-bit value determines the QoS level. For this example, we will not configure QoS as we are using VLAN tagging for the Voice VLAN

Details regarding various Avaya IP Phone DHCP and provisioning file parameters are listed in Appendix A

2.3Auto Configuration with a Stackable Ethernet Routing Switch – with traffic filters for QoS and optional LLDP MED Policy

LLDP-MED Policy can be used with our without ADAC. If you choice to not use ADAC, by default, there will be no QoS for the voice traffic. There are a number of ways to provide QoS for the voice traffic such as:

Creating a new interface group with a class of trusted and applying this interface group to either all ports or at minimum the uplink ports, call server ports, and all ports connected to IP phones. This is simplest method, but, it also trusts all traffic which may or may not be acceptable

oCould create a filter to look for the data VLAN and remark to Standard service

Leave all ports with the default Interface Group with a class of untrusted and add a filter to look for the voice VLAN and remark traffic to Premium service.

For this configuration example, we will simply create a traffic profile to match the voice VLAN and set the CoS to Premium (p-bit value of 6 and DSCP value of 46).

This configuration example is in reference to diagram 1.

2.3.1.6 Configure Management IP address on switch

An IP address can be added in one of two ways. If the switch is strictly used as a Layer 2 switch, then an IP address can be added via the Layer 2 method using the ACLI command ip address <switch|stack> <IP address> netmask <mask> default-gateway <default GW>.

2.3.1.6.1 Adding Management IP - Layer 2

ERS-Stackable Step 1 – Set the IP address of the switch

ERS-Stackable(config)#vlan mgmt 201

2.3.1.8 QoS

There are several options you can deploy to add QoS for the voice traffic.

Assign QoS class of trusted to all ports – easiest to implement and trust’s all traffic including soft clients

Assign QoS class of trusted to all ports and adding a filter to remark the data traffic if you do not trust traffic from the data VLAN – note, will will also remark soft clients to best effort

Set all access ports as untrusted (default setting), set uplink ports as trusted, and add a filter to remark the voice traffic to CoS level of Premium – only provides QoS for the voice VLAN

Enable Auto QoS – only supported on limited Avaya products

oCS1000, CS2100, BCM, and/or SRG call servers

Enable ADAC – automatically provides QoS only to the voice VAN – please see next two sections regarding ADAC provisioning

For this example, we will simply trust all traffic by setting all ports as trusted ports. This is the easiest method for applying QoS for both untagged soft clients and tagged hard clients. We will also provision the switch with queue set 4 providing 1 strict queue and 3 WRR queues which may be more acceptable to handle voice, data, and video if the switch is either a ERS 4000 or ERS 5000; by default, the ERS 2500 uses queue set 4 while the ERS 4000 and ERS 5000 uses queue set 2. Otherwise, if the switch is only supporting voice and data, you can use the default queue set 2 in reference to the ERS 4000 and ERS 5000.

If you are using an Avaya Ethernet Routing Switch 5000 or Ethernet Routing Switch 4000 (release 5.4 or higher), the default queue set (queue set 2) uses two strict queues with large buffers. If you wish, you can provision another queue set if 2 queues do not

and one strict queue may be more acceptable to handle voice, video, and data. If you do wish to use queue set 4, enter the ACLI command qos agent queue-set 4. You can use the ACLI command show qos queue-set to view the make up for each queue set.

The ERS 2500 only supports one queue set, queue set 4, which supports one strict queue and three weighted-round-robin (WWR) queues.meet your needs. For example, queue set 4 which will provide three weighted queues

ERS-Stackable Step 1 – Change from default queue set (queue set 2) to queue set 4 and reset the switch. Note, this only applies to the ERS 5000 or ERS 4000

ERS-Stackable(config)#qos agent queue-set 4

QoS queue setting isn't effective until after reset.

ERS-Stackable Step 2 – Create a new interface group with a class of trusted

ERS-Stackable(config)#qos if-group name trusted class trusted

ERS-Stackable(config)#qos if-assign port ALL name trusted

Aug 2012	Avaya Inc. – External Distribution	21

avaya.com

If you wish, you can provision the switch to remark the data traffic to best effort if you do not trust the traffic from the data VLAN.

ERS-Stackable Step 1 – Traffic Profile Option. Configure either a traffic profile or ACL to remark the data VLAN with a QoS level of Standard depending on switch model. Assuming ERS-Stackable is an ERS 4000 or ERS 5000, it is recommend to use traffic profiles

ERS-Stackable(config)#qos traffic-profile classifier name one vlan-min 1002 vlan-max 1002 ethertype 0x800 update-dscp 0 update-1p 0

ERS-Stackable(config)#qos traffic-profile set port 1-13 name one

ERS-Stackable Step 1 – ACL Option. Configure either a traffic profile or ACL to remark the data VLAN with a QoS level of Standard depending on switch model. ACL’s can be used on a ERS 2500, ERS 4000, or ERS 5000 where it is recommended to use traffic profiles over ACL’s if supported on the switch

ERS-Stackable(config)#qos l2-acl name one vlan-min 1002 vlan-max 1002 ethertype

0x800 update-dscp 0 update-1p 0

ERS-Stackable(config)#qos l2-acl name one ethertype 0x800 drop-action disable

ERS-Stackable(config)#qos acl-assign port 1-13 acl-type l2 name one

2.3.1.9 Spanning Tree Configuration

ERS-Stackable Step 1 – Enable STP Fast-Start and BPDU filtering on port 3 to 11

ERS-Stackable(config)#interface fastEthernet all

ERS-Stackable(config-if)#spanning-tree port 3-11 learning fast

ERS-Stackable(config-if)#spanning-tree port 3-11 bpdu-filtering timeout 0

ERS-Stackable(config-if)#spanning-tree port 3-11 bpdu-filtering enable

2.3.1.10Add LLDP-MED Network Policy – Optional for ERS 3500, ERS 4000 or ERS 5000

As an option, you can enable LLDP-MED with Network Policy to provision the voice VLAN without having to use DHCP. In addition, you can also provision LLDP vendor specific settings to provision the call server and file server (only for the Avaya 96xx IP phones as per this configuration example).

Note that the ERS 2500 requires ADAC must be used to enable LLDP MED. The ERS 3500 requires software release 5.0.1 or higher to use LLDP-MED without ADAC.

ERS-Stackable Step 1 – Add LLDP MED Network Policy

ERS-Stackable(config)#interface fastEthernet 3-11

ERS-Stackable(config-if)#lldp med-network-policies voice tagging tagged vlan-id

805

ERS-Stackable(config-if)#exit

2.3.1.10.1LLDP Tx-TLVs – Older Software Releases

Depending on the software release used, it may be nessessary to enable LLDP TLVs. This does not apply to the ERS 4000 as of release 5.5, ERS 3500 as of release 5.0.1, and ERS 5000 as of release 6.3 from a factory default setting, but, to verify if the TLVs are enabled or not, please enter the ACLI commands show lldp port 3-11 & show lldp tx-tlv.

ERS-Stackable Step 1 – Enable LLDP TLVs

ERS-Stackable(config)#interface fastEthernet 3-11

ERS-Stackable(config-if)#lldp tx-tlv local-mgmt-addr port-desc sys-cap sys-desc sys-name

ERS-Stackable(config-if)#lldp status txandRx config-notification

ERS-Stackable(config-if)#lldp tx-tlv med extendedPSE inventory location medcapabilities network-policy

ERS-Stackable(config-if)#exit

2.3.1.10.2Enable LLDP Vendor Specific settings

Up to 8 call-servers and up to 4 file-servers can be defined. Note that, for this configuration example, the LLDP vendor specific settings only apply to the Avaya IP Phones.

ERS-Stackable Step 1 – Add LLDP Vendor Specific options

ERS-Stackable(config)#lldp vendor-specific avaya call-server 1 10.30.30.20

ERS-Stackable(config)#lldp vendor-specific avaya file-server 1 192.168.50.100

ERS-Stackable(config)#interface fastEthernet 3-11

ERS-Stackable(config)#lldp vendor-specific avaya dot1q-framing tagged

ERS-Stackable(config)#exit

2.3.1.11 Enable IP Anti-Spoofing and IP Source Guard – Optional

To prevent IP spoofing attacks, it is recommended to enabled IP DHCP Snooping and IP Arp Inspection. In addition, it is recommended to enabled IP Source Guard which prevents a host from spoofing a source IP other than that assigned by DHCP.

ERS-Stackable Step 1 – Enable IP DHCP Snooping for voice VLAN 805 and data VLAN 1002

ERS-Stackable(config)#ip dhcp-snooping vlan 805

ERS-Stackable(config)#ip dhcp-snooping vlan 1002

ERS-Stackable(config)#ip dhcp-snooping enable

ERS-Stackable Step 2 – Enable IP Arp Inspection for voice VLAN 805 and data VLAN 1002

ERS-Stackable(config)#ip arp-inspection vlan 805

Aug 2012	Avaya Inc. – External Distribution	23
