ctBridgeTransTrEnetIBMSap

Module: CTRON-BRIDGE-MIB

OID (symbolic): CTRON-BRIDGE-MIB::ctBridgeTransTrEnetIBMSap

OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.7.7.1.2

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: The SAP value of an IBM protocol. The bridge will translate all Token Ring/802.5 packets without a snap header having this SAP value to Ethernet packets with the Ethernet type field set to 80D5. The SAP value is one octet.

What is ctBridgeTransTrEnetIBMSap?

This read-write octet string holds the one-byte SAP value of an IBM protocol; the bridge translates any Token Ring/802.5 packet lacking a SNAP header but carrying this SAP value into an Ethernet packet with its type field set to 80D5 (the IBM NetBIOS/SNA Ethernet type). An administrator configures this to ensure legacy IBM SNA or NetBIOS traffic identified by SAP is correctly re-encapsulated when crossing from Token Ring to Ethernet. For example, to bridge an IBM mainframe's SNA traffic from a Token Ring segment onto an Ethernet LAN, the admin sets this SAP value to match the SNA control SAP used by the mainframe's LLC layer.
