Tell the device which image to load on the next reboot. This ensures it picks the new IOS.
Exceptional performance for Quad-Supervisor Virtual Switching System (VSS) setups. Certain custom security ACL policies may require structural
Deploying the 15.5(1)SY10 binary addresses critical vulnerabilities historically found in earlier 15.5(1)SY iterations, including: Control Plane memory leaks during heavy SNMP polling. SSH server key exchange bugs.
Connect to your active Supervisor Engine via secure copy protocol (SCP) or TFTP and move the binary to the local boot storage:
For VSS setups with Quad-SUPs, EFSU allows for a significantly reduced downtime compared to traditional cold reloads. The upgrade process involves: Upgrading the standby supervisors. Switching over. Upgrading the former active supervisors. : 64 indicates it is the 64-bit version of the software
