Configuring and Viewing ISDP Information

The Industry Standard Discovery Protocol (ISDP) is a proprietary Layer 2 network protocol which inter‐operates with devices running the Discovery Protocol (DP). ISDP is used to share information between neighboring devices. TejNOS-EN software participates in the DP protocol and is able to both discover and be discovered by other DP supporting devices.

The following pages are accessible from this ISDP folder:

Global Configuration

From the ISDP Global Configuration page, you can configure the ISDP settings for the switch, such as the administrative mode.

isdp_global

ISDP Global Configuration

Field	Description
ISDP Mode	Use this field to enable or disable the Industry Standard Discovery Protocol on the switch.
ISDP V2 Mode	Use this field to enable or disable the Industry Standard Discovery Protocol v2 on the switch.
Message Interval	Specifies the ISDP transmit interval. The range is (5–254). Default value is 30 seconds.
Holdtime Interval	The receiving device holds ISDP message during this time period. The range is (10–255). Default value is 180 seconds.
Device ID	The Device ID advertised by this device. The format of this Device ID is characterized by the value of Device ID Format object.
Device ID Format Capability	Indicates the Device ID format capability of the device. serialNumber: Indicates that the device uses serial number as the format for its Device ID. macAddress: Indicates that the device uses layer 2 MAC address as the format for its Device ID. other: Indicates that the device uses its platform specific format as the format for its Device ID.
Device ID Format	Indicates the Device ID format of the device. serialNumber: Indicates that the value is in the form of an ASCII string containing the device serial number. macAddress: Indicates that the value is in the form of Layer 2 MAC address. other: Indicates that the value is in the form of a platform specific ASCII string containing info that identifies the device.

Cache Table

From the ISDP Cache Table page, you can view information about other devices the switch has discovered through the ISDP.

isdp_cache

ISDP Cache

Field	Description
Device ID	Displays the string with Device ID which is reported in the most recent ISDP message.
Interface	Displays the interface that this neighbor is attached to.
IP Address	The (first) network‐layer address that is reported in the Address TLV of the most recently received ISDP message.
Version	Displays the Version string for the neighbor.
Holdtime	Displays the ISDP holdtime for the neighbor.
Capability	Displays the ISDP Functional Capabilities for the neighbor.
Platform	Displays the ISDP Hardware Platform for the neighbor.
Port ID	Displays the ISDP port ID string for the neighbor.
Protocol Version	Displays the ISDP Protocol Version for the neighbor.
Last Time Changed	Displays when entry was last modified.

Interface Configuration

From the ISDP Interface Configuration page, you can configure the ISDP settings for each interface.

NOTE: If ISDP is enabled on an interface, it must also be enabled globally in order for the interface to transmit ISDP packets. If the ISDP mode on the ISDP Global Configuration page is disabled, the interface will not transmit ISDP packets, regardless of the mode configured on the interface.

isdp_interface

ISDP Interface Configuration

Field	Description
Interface	Select the interface with the ISDP mode status to configure or view.
ISDP Mode	Use this field to enable or disable the Industry Standard Discovery Protocol on the selected interface.

Statistics

From the ISDP Statistics page, you can view information about the ISDP packets sent and received by the switch.
