Warm Upgrade - Dell Force10 S4810P Configuration Manual

• Hot-lock IP ACLs (supported on E-Series, C-Series, and S-Series) allow you to append rules to and
delete rules from an Access Control List that is already written to CAM. This behavior is enabled by
default and is available for both standard and extended ACLs on ingress and egress. For information

Warm Upgrade
Warm software upgrades use warm failover, which means that FTOS reboots the secondary RPM and all
line cards and SFMs. The chassis remains online during the upgrade, but forwarding is interrupted, as
shown in Table 21-4, "Control Plane and Data Plane Status during Warm Upgrade," in High
FTOS supports warm software upgrades under two conditions:
• between consecutive feature releases where only the second digit differs between the running FTOS
version number and the upgrade version number. For example, an upgrade from FTOS version 7.6.1.0
to 7.7.1.0 is warm.
• between two consecutive maintenance releases of the same feature release. For example, upgrading
from 7.7.1.0 to 7.7.1.1 is warm.
