The ERS 2500 delivers 3 flexible options to meet customer needs

Flexible option to move to stacking

Standalone Stacked

• No need to purchase additional hardware

• Stacking is enabled via a software license

• Grow your network when/if YOU want to

• Units with stacking pre-enabled are available

• Ready to stack immediately

• No need for a stacking license Stack Enabled

Scalability from Day 1

Use ERS 2500s as single units

Standalone

• Ideal for smaller sites

• Budget-friendly option

Getting Started Standalone or Stacking

10

ERS 2500s use the rear 1000BaseTX ports as stacking ports– Rear ports offer the flexibility to be used as either normal Gigabit ports or as

stacking ports.– Gigabit grade (Cat5E/Cat6) RJ-45 cabling is used to create the stacking ring– Stack up to 8 units high for 384 10/100 user ports and 16 Gigabit ports

Ethernet Routing Switch 2500 SeriesStacking Implementation

11

– “Stacking Mode” must be configured on the rear ports before switches are connected together in a stack (there is no “auto-detection”).

– The Base unit must have Unit Select switch set to ON (one switch only)

– Each ERS2500 switch ships with a 46cm (1.5 foot) stack cable (black Cat5E cable).

– Additional cables of 1.5m (5’) and 3m (10’) are also be available for separate purchase from Avaya and are like “stack return” cables.

– Customers are permitted to use their own cables and longer lengths up to 100m (at customer’s risk, not “officially” supported by GNTS).

VLAN Config Control

Automatic AutoPVID Flexible Strict

(default)

Operations As you change the vlan the PVID changes accordingly

As you add a Vlan the PVID changes to the new vlan

As you add a Vlan the PVID remains set to the first vlan

To change Vlan the port has to be removed from the previous vlan

# of VLANs

/Access port

One only Multiple Multiple One Only

*Note: Applies to Untag All and Tag PVID Only ports


Vlan Configuration Control

Automatic :-– VLAN Membership: Automatically adds an untagged port to

a new VLAN and automatically removes it from any previous VLAN membership.

– PVID of the port: is automatically changed to the VID of the VLAN it joins.

AutoPVID :-– When an untagged port is added to a new VLAN, the port is

added to the new VLAN and the PVID is assigned to the new VID without removing it from any previous VLAN memberships. Using this option, an untagged port can have membership in multiple VLANs


Vlan Configuration Control

Flexible:-– Similar to AutoPVID. When this option is used, an untagged

port can belong to an unlimited number of VLANs.

– Any new additions of an untagged port to a new VLAN does not change the PVID of that port

Strict:-– The factory default, this selection restricts the addition of an

untagged port to a VLAN if it is already a member of another VLAN.

– To add an untagged port to a new VLAN, a port must be remove from all other VLANs of which it is a member before adding it to the new VLAN. The PVID of the port is changed to the new VID to which it was added.

IP Local and Static RoutingFeature Overview

Support up to 256 locally configured routing instances. Provides static route support Supports IP blocking (for different stack failures) Allows the switch to be managed through any IP address that has been

assigned to any VLAN interface (not just the management VLAN).– When IP routing is enabled, the existing Switch / Stack IP address is

assigned to the management VLAN interface.

L3 Routing BootP/DHCP Relay

In order to obtain an IP address a BootP or DHCP client will broadcast the request on the local subnet. When routing is enabled on the VLAN, these broadcasts are not forwarded by the router.

This is where the Bootp/DHCP relay is applicable. The relay agent intercepts these Bootp/DHCP requests and forwards then to the specified host or broadcast address on another routed VLAN.

Up to 10 DHCP/BootP servers may be identified as destinations to the relay.

Advanced QoSFeature Overview

QoS functions supported include: – L2-L4 traffic classification, – filtering (forward/drop), – marking/remarking of DSCP, – Policing/metering and – egress Shaping.

QoS configuration fully supported in CLI and EDM (GUI).

Advanced QoS support across all current stackable switching families.

79

DiffServ and 802.1p are the underlying technology for all QoS configurations.

The ERS Series supports the following QoS classes:– Critical and Network classes have the highest priority over all other traffic.– Premium class is an end-to-end service functioning similarly to a virtual

leased line. Traffic in this service class is normally guaranteed an agreed-upon peak bandwidth. Traffic requiring this service must be shaped at the network boundary in order to undergo a negligible delay and delay variance. This service class is suitable for real-time applications, such as video and voice over IP. The recommended PHB for this service is the Expedited Forwarding (EF) PHB.

– Platinum, Gold, Silver, and Bronze classes use the Assured Forwarding (AF) PHB. These classes are used for real-time, delay-tolerant traffic and non-real-time, mission-critical traffic.

– Standard class is the best-effort IP service with an additional, optional use of traffic classification that is used at the network boundary to request a better effort treatment for packets that are in-profile (packets that do not break the service agreements between the user & the service provider).

Advanced QoSQoS Concepts

80

Port-based Quality of Service: policies are applied directly to individual ports.

A port-based Quality of Service environment allows for the more direct application of Quality of Service policies and eliminates the need to group ports together when assigning policies.

Role-based Quality of Service: individual ports are first assigned to a role and that role was assigned a policy. A role is a collection of ports defined within the same interface group. They share settings. For example, all ports are defined as untrusted.

Port-based and role-based policies can be applied to same port; however the switch administrator is responsible for the proper division of resources across the individual policies.

At factory default, ports are assigned to the default interface group (role combination), which is named allQoSPolicyIfcs.

Advanced QoSQoS Concepts cont…

81

Interface groups are used in the creation of role-based policies. Role-based policies differ from port-based policies in the fact that role-

based policies group ports together to apply a common set of rules to them.

Each port can belong to only one interface group. When you move a port to another interface group (role combination),

the classification elements associated with the previous interface group are removed and the classifications elements associated with the new interface group are installed on the port.

At factory default, ports are assigned to the default interface group (role combination), which is named allQoSPolicyIfcs.

All ports must be removed from an interface group before it is deleted. An interface group cannot be deleted when it is referenced by a policy.

Advanced QoSInterface Groups

82

The classifications of trusted, untrusted, and unrestricted actually apply to groups of ports (interface groups).

Trusted interfaces — IPv4 traffic received on trusted interfaces is re-marked at the layer 2 level, that is, the 802.1p user priority value is updated based on the DSCP value in the packet at ingress and the installed DSCP-to-CoS mapping data. The DSCP value is not updated.

Untrusted interfaces — IPv4 traffic received on untrusted interfaces is re-marked at the layer 3 level—that is, the DSCP value is updated.

Unrestricted interfaces – Does not change DSCP or 802.1p setting.

Important note on layer 4 port ranges:– Port range specifications are limited due to the way bit masking operates on

the switches. – Example: ‘min’ port range set first then becomes the “bit boundary” for the

‘max’ range. If you start the ‘min’ at port 80 (1010000 binary), the next ‘max’ range can be 81 (1010001), or 83 (1010011), or 87 (1010111), or finally - 95 (1011111). IE: bit mask/wildcards are added by column weight upto the first “1” set in the minimum range value.
