saCmMtaDhcpPktcOption
Module: SA-CM-MTA-MIB
OID (symbolic): SA-CM-MTA-MIB::saCmMtaDhcpPktcOption
OID (numeric): 1.3.6.1.4.1.1429.78.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object must only be set via the CM configuration file during the provisioning process. After CM is operational, this object can not be set via SNMP. 0: CM and MTA will accept only PacketCable option 122. If option 122 is not included in CM DHCP OFFER, MTA will not start. 1: CM and MTA will accept 122 or 177 or none. If DHCP OFFER contains 122 or 177, MTA will process it. 2: CM and MTA will accept only PacketCable option 177. If option 177 is not included in CM DHCP OFFER, MTA will not start. This MIB is saved into modem's non-vol memory and the new value is active after the modem registers and reboots again (DHCP comes before config file parsing). Note: Equivalent of VSIF 64 Note: This object can be set via the CM configuration file ONLY.
What is saCmMtaDhcpPktcOption?
This enumerated value controls which PacketCable DHCP option, 122, 177, or either, the cable modem and MTA will accept during DHCP negotiation, and can only be set via the CM configuration file. Admins select the option matching their provisioning infrastructure's DHCP server configuration, since a mismatch, like requiring 122 when the server only sends 177, prevents the MTA from starting. The default require122(0) means the MTA will refuse to start unless DHCP option 122 is present in the CM's DHCP OFFER; setting it to requireNone(1) relaxes that requirement to accept either option or neither.
