Minimum RAM required: 4 GB (recommended) Bootloader requirement: ROMMON must be 1.6 or later for this version. End-of-Sale status: 3.6.10E is an old release (circa 2016). Cisco recommends upgrading to 16.x or later (Denali, Everest 16.6+, or Gibraltar 16.12+ for security patches). SMU support: No longer receiving Software Maintenance Upgrades.
