Introduction to ciscocm.free_common_space_v1.10.k4.cop.sha512
This SHA512-verified Cisco Options Package (COP) provides automated storage reclamation for Cisco Unified Communications Manager (CUCM) 15.5 deployments. Designed to address persistent disk space challenges in large-scale collaboration clusters, it implements intelligent log rotation and temporary file cleanup aligned with ITU-T X.1812 standards for telecommunication system maintenance.
The “free_common_space” utility targets 14 critical storage areas including /common/logs, /var/log/core dumps, and inactive voicemail cache directories. As part of Cisco’s Proactive Maintenance Framework, it generates RFC 8428-compliant audit trails while maintaining FIPS 140-3 Level 1 validated data sanitization protocols.
