Category: Protocol: X.25, Vendor: Allied Telesis

Description: Provides management objects for X.25 packet-switching protocol interfaces on Allied Telesis iTouch network devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ITOUCH-X25-MIB?

ITOUCH-X25-MIB provides management objects for the X.25 packet-switching protocol on Allied Telesis iTouch network devices, part of the vendor's legacy WAN protocol support. It covers X.25 link and virtual-circuit configuration and statistics for serial WAN interfaces. Monitoring focus here is protocol/software-layer health rather than physical hardware—link state, packet/error counts, and virtual circuit status reveal whether an X.25 WAN connection is stable or degraded. It likely complements the standard X.25 MIB (RFC 1382). The ITOUCH-X25-MIB MIB is typically deployed on legacy WAN links using X.25 packet switching on Allied Telesis routers, common in older telecom or serial-network environments.

IPNetwork Monitor allows you to monitor SNMP objects defined in ITOUCH-X25-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

iTouch Communications (later Black Box) routers with X.25 WAN interfaces

Monitoring Examples

No sample object names were supplied for this MIB. Based on its purpose, an admin would expect to poll X.25 link-layer and virtual-circuit status tables to detect circuit resets or elevated retransmission/error counts indicating a degraded WAN link, though exact object names cannot be confirmed without a sample list.

What Can Be Monitored

X.25 virtual circuit status
X.25 link layer statistics
packet/frame error counts
call setup/clear counts

INT xX25ChannelLowPVC	1.3.6.1.4.1.33.20.4.1.2	INTEGER	read-write	Lowest PVC channel. Setting it to zero indicates 'none', and will also set the xX25ChannelHighPVC to zero. If set to a non-zero value and xX25ChannelHighPVC is zero, xX25ChannelHighPVC will be set to the same value. Otherwise, xX25ChannelLowPVC must be less than or equal to xX25ChannelHighPVC.
INT xX25ChannelHighPVC	1.3.6.1.4.1.33.20.4.1.3	INTEGER	read-write	Highest PVC channel. Setting it to 0 indicates none, and will also set the xX25ChannelLowPVC to 0. If set to a non-zero value and xX25ChannelLowPVC is zero, xX25ChannelLowPVC will be set to the same value. Otherwise, xX25ChannelHighPVC must be less than or equal to xX25ChannelLowPVC.
INT xX25ChannelNetwork	1.3.6.1.4.1.33.20.4.1.4	INTEGER	read-write	The type of network being run.

INT xX25VcCfgClearFacilities	1.3.6.1.4.1.33.20.6.1.9	INTEGER	read-write	Control to clear the VC call facilities string. In response to a get-request or get-next-request, the agent always returns 'ready' for this value. Setting the value to 'ready' has no effect. Setting it to 'execute' causes the string to be cleared.
