Registered as CSPMLockMgr, the lock manager of Cisco's long-discontinued Secure Policy Manager.
IANA assigns 1272 on TCP and UDP to cspmlockmgr ("CSPMLockMgr"), registered by Ibtsam Mahfouz. The name matches Cisco Secure Policy Manager, a centralised firewall/VPN policy product Cisco retired long ago; its lock-manager component used this port. Cisco no longer ships or documents the product, so a listener on 1272 today is almost certainly unrelated software that took a free registered port.
Expose with care
Any surviving instance would be an end-of-life management component with no security maintenance; identify what is actually listening and keep it off public networks.
