System Capacities

System capacities vary across the range of platforms that support the SBC. To query the current system capacities for the platform you are using, execute the show platform limits command.

SIP Interface and Realm Limits for vSBC

The number of Realms and SIP interfaces that you can configure on a vSBC is limited by the amount of VM memory. A maximum of 1500 Realms and SIP interfaces can be configured for every 1GB of system memory.

Note:

These limits also apply to the SR.

Static Trusted and Untrusted ACL Limits for vSBC

When deployed as a virtual SBC or a virtual SR, the SBC supports static ACL entry counts based on virtual machine 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.

Note:

These limits also apply to the SR.
