ESA port connectivity is supported on most FP3-based IOMs and all FP4-based cards. For a list of supported platforms or cards, contact your Nokia representative.
An SR system can support up to 15 active and one standby ESA-VMs for AA.
AA ESA-VM software upgrades are part of the ISSU functionality. Upgrades to AA software, for example to activate new protocol signatures, do not impact other ESA-VMs on the same ESA or on other traffic on the same IOM, nor do upgrades impact the router itself (for example, a new AA software image can be downloaded to an ESA-VM without a need to upgrade other software images).
The ESA version must match the build release version of the host IOM.
