System Capacities

System capacities vary across the platforms that support the ESBC. Use the show platform limits command to query your system's capacities.

Virtual platforms include the following limitations.

SIP Interface and Realm Limits

On virtual platforms, the number of realms and SIP interfaces is limited by the amount of VM memory. You can configure a maximum of 1500 realms and SIP interfaces for every 1GB of system memory.

Static Trusted and Untrusted ACL Limits

On virtual platforms, the number of static ACL entries is limited by the amount of VM memory. Deployments under 8GB of memory support 8K trusted and 4K untrusted entries. When memory is:

  • Between 8GB and 64GB, supported entries include:
    • Trusted static ACLs is 1024 per GB
    • Untrusted static ACLs is 512 per GB
  • Greater than 64GB, supported entries include:
    • Trusted static ACLs is 65536
    • Untrusted static ACLs is 32768

Dynamic ACL entries are independent of this support.
