sprotoArpTranslate
Module: CTATX-MIB
OID (symbolic): CTATX-MIB::sprotoArpTranslate
OID (numeric): 1.3.6.1.4.1.97.3.17.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: These options are intended to compensate for any like- ly implementation of internet ARP on 802.5 token ring. If set to bitswap1(2), then embedded MAC addresses for ARP packets with hardwareType 1 (Ethernet) will be bitswapped. If bitswap6(3) then embedded MAC addresses for ARP packets with hardware type 6 (IEEE 802) will be bitswapped. If bitswap61(4) then both type-1 and type-6 ARP packets will be bitswapped. If oneto6(5), then in- coming type-6 ARP packets will be changed to type-1 and outgoing type-1 ARP packets will be changed to type-6, both without bitswapping. If oneto6swap(6), then incom- ing type-6 ARP packets will be converted to type-1 and outgoing type-1 to type-6, with embedded addresses bitswapped.
This option only applies to token ring ports. The fac- tory default for all ports is none(1).
What is sprotoArpTranslate?
This read-write enumerated INTEGER selects how embedded MAC addresses in ARP packets are bit-swapped when bridging between Ethernet (hardware type 1) and 802/Token Ring (hardware type 6) networks, offering options like bitswap1, bitswap6, bitswap61, oneto6, and oneto6swap to compensate for differing ARP implementations. An admin configures this specifically to fix ARP resolution failures that occur because Ethernet and Token Ring represent MAC addresses in different bit orders. Setting sprotoArpTranslate to bitswap61(4) would resolve a mixed Ethernet/Token Ring network where ARP addresses for both hardware types are appearing incorrectly on the other segment.
