hcxStuGlobalSwImage
Module: COM21-HCXTOP-MIB
OID (symbolic): COM21-HCXTOP-MIB::hcxStuGlobalSwImage
OID (numeric): 1.3.6.1.4.1.1141.2.5.20
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: This attribute provides an easy way to change the configured software image for all configured ComPorts without having to modify hcxStuConfSwImage of individual ComPorts. When this attribute is written to by the user, the hcxStuConfSwImage attribute for all configured ComPorts will be automatically modified to reflect this value. However, this is only a one-time action. The user is free to modify the hcxStuConfSwImage attribute of individual ComPorts to other values. Since this attribute only affects configured ComPorts, it does not interfere with hcxStuDefCom21SwImage or hcxStuDef3ComSwImage from com21HcxStuDefaultGroup. Default is 0.0.0.0. Also, it will reset back to 0.0.0.0 upon a ComController reboot.
What is hcxStuGlobalSwImage?
This read-write DisplayString (16 bytes) lets an admin push a software image assignment to every configured ComPort on the ComController in a single set, rather than editing each ComPort's hcxStuConfSwImage individually, though it is only a one-time bulk action. It is useful for rolling out a firmware update fleet-wide without scripting per-port SNMP sets. For example, an admin sets this to "hcx_v4.2.img" to assign that firmware to every currently configured ComPort in one operation, then still adjusts a few individual ports afterward as needed.
