Nortel Networks 2500 Series manual Ascii configuration file

74System configuration software features

ASCII configuration file

You can also store the configuration parameters of a switch/stack as an ASCII configuration file and retrieve the stored file to automatically configure a replacement switch/stack.

Autotopology

You can enable the Optivity* Autotopology* protocol on the Ethernet Routing Switch 2500 Series using the CLI. For more information about Autotopology, go to the Nortel support site: www.nortel.com/support (The product family for Optivity and Autotopology is Data and Internet.)

Link Layer Discovery Protocol (IEEE 802.1ab)

Release 4.1 software supports the Link Layer Discovery Protocol (LLDP) (IEEE 802.1ab), which lets stations connected to a LAN to advertise their capabilities to each other, enabling the discovery of physical topology information for network management. LLDP-compatible stations can consist of any interconnection device including PCs, IP Phones, switches, and routers. Each LLDP station stores LLDP information in a standard Management Information Base (MIB), making it possible for the information to be accessed by a network management system (NMS) or application.

Each LLDP station:

•advertises connectivity and management information about the local station to adjacent stations on the same 802 LAN (802.3 Ethernet with Ethernet Routing Switch 2500)

•receives network management information from adjacent stations on the same LAN

ATTENTION

LLDP works in stack mode.

LLDP makes it possible to discover certain configuration inconsistencies or malfunctions that can result in impaired communications at higher layers. For example, it can be used to discover duplex mismatches between an IP Phone and the connected switch.

LLDP is compatible with IETF PROTO MIB (IETF RFC 2922).

Figure 22 "How LLDP works" (page 75) shows an example of how LLDP works in a network.
