cdx6500X25CfgOptions

Module: X25-OPT-MIB

OID (symbolic): X25-OPT-MIB::cdx6500X25CfgOptions

OID (numeric): 1.3.6.1.4.1.449.2.1.2.1.1.2.1.31

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: Select options on this X.25 port as follows: NONE - no option specified. 1980 - use X.25 1980. NUI - perform network user identification validation check. PDN - connected to Public Data Network. CUD - use call user data subaddressing. IBAR - bar all calls coming in from X.25 port user. OBAR - bar all calls going out to X.25 port user. CBCK - allow routing inbound calls back out this port. CUG - check closed user group; otherwise, CUG passes transparently. CAUSE - pass cause, diagnostic, code in outbound packets. HOLD - hold calls over link restart. NRST - do not send restart packet on link-up. BKUP - this is a backup port to be activated if other ports are down. INL - inter-node link. Link goes to another Vanguard device.INL may be a poor choice for high speed links.INLB is set with INL to improve the performance of high speed links.INLB can be configured in the More X25 Options parameter. INLA - set with INL option when an X.25 link connection is to a 6500 node using 2.12.04 or earlier. DELAY - enable Delay and Path trace on this link (link must connected to Rel. 4.xx node). Any combination of above specified by summing (e.g. 1980+NUI+. . .).

What is cdx6500X25CfgOptions?

A multi-value option string selecting X.25 port behaviors such as using X.25 1980, NUI validation, PDN connection, call-user-data subaddressing, in/out call barring, closed user group checking, cause-code passing, hold-over-restart, and inter-node link tuning; multiple options are combined by summing (e.g. 1980+NUI).

Start monitoring X.25 packet-switched network access devices/routers, e.g. cdx6500 platform (port-to-protocol-group config status) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the X25-OPT-MIB::cdx6500X25CfgOptions OID value, configure state conditions and alerts, and monitor any X.25 packet-switched network access devices/routers, e.g. cdx6500 platform (port-to-protocol-group config status) from a single console.
