40 Summit 200 Series Switch Installation and User Guide
ExtremeWare Overview
If Extreme switches running ESRP are connected to layer 2 switches that are not manufactured by
Extreme Networks (or Extreme switches that are not running ExtremeWare 4.0 or above), the fail-over
times seen for traffic local to the segment may appear longer, depending on the application involved
and the FDB timer used by the other vendor’s layer 2 switch. As such, ESRP can be used with layer 2
switches from other vendors, but the recovery times vary.
The VLANs associated with the ports connecting an ESRP-aware switch to an ESRP-enabled switch
must be configured using an 802.1Q tag on the connecting port, or, if only a single VLAN is involved, as
untagged using the protocol filter
any . ESRP will not function correctly if the ESRP-aware switch
interconnection port is configured for a protocol-sensitive VLAN using untagged traffic.
ESRP routing is supported in stacked configurations only on the master switch.
Software Licensing
Some Extreme Networks products have capabilities that are enabled by using a license key. Keys are
typically unique to the switch, and are not transferable. Keys are stored in NVRAM and, once entered,
persist through reboots, software upgrades, and reconfigurations. The following sections describe the
features that are associated with license keys.
Feature Licensing
Summit 200 series switches support software licensing for different levels of functionality. In
ExtremeWare version 6.2e.2, feature support is separated into two sets: Edge and Advanced Edge. Edge
is a subset of Advanced Edge.
Edge Functionality
Edge functionality requires no license key. Summit 200 series switches have Edge functionality without
the requirement of a license key. Edge functionality includes all switching functions, and also includes
all available layer 3 QoS, access list, and ESRP-aware functions. Layer 3 routing functions include
support for:
• IP routing using RIP version 1 and/or RIP version 2
• IP routing between directly attached VLANs
• IP routing using static routes
Advanced Edge Functionality
The Advanced Edge license enables support of additional functions, including:
• Rate-limiting ACLs
• IP routing using OSPF
• EAPS Edge (cannot be a core node on the ring)
• Network login
• RADIUS and TACACS+ command authentication
• Network Address Translation (NAT)
