Number of IP Addresses per Call Leg Size

The table below defines the number of

Spacevars
0series2
call legs supported for a given number of IP Addresses on different SBC platforms are as follows:

  • Spacevars
    0series2
    , assuming UDP ports 4,000 through 64,444 are configured for media port usage - See table below.
  • Spacevars
    0model5
     with 10GE interfaces - Supports a maximum of 75000 sessions, requiring 4 IP addresses per call leg.
  • Spacevars
    0product2
    - Supports a maximum of 64000 sessions, requiring 3 IP addresses per call leg.

For 
Spacevars
0series2
media resource allocation scenarios, the 
Spacevars
0product
requires a minimum of 10 IP addresses configured to support 150,000 call legs (one Primary IP address plus 9 alternate IP addresses in non-VLAN configuration).

For example, to use 100,000 call legs you must configure at least six (6) IP addresses because five IP addresses will only allow up to 96,000 call legs through the

Spacevars
0product
.

The  

Spacevars
0series4
supports configuring up to 14 alternate media addresses. For more details, see Alternate Media IP Addresses Support.

Configuration Limits

The 

Spacevars
0series2
supports a large number of configurable objects and is capable of supporting from a few very large customers to thousands of small customers. Important details about the provisioning system include:

  • Interactive provisioning of configuration objects (such as commands typed at the CLI or entered in the EMA or EMS) does not affect call handling or capacity.
  • Provisioning behavior does not depend on the number of existing entities. The addition of the 10,000th instance is roughly comparable to adding the 1st such instance.
Note
titleCaution

Bulk or non-interactive provisioning may affect call handling. Operations such as sourcing a CLI script with many configuration commands (or even a few commands affecting particularly large objects) should only be done during a maintenance window or at non-busy-hour intervals. 

Provisioning Limits

Spacevars

Footnotes

1 - Includes approximately 10,000 IP ACLs for signaling ports (2 x 4,000 SIP, 2,000 H323) and 100 IP ACLs for OAM. A maximum of 35,648 IP ACLs are allowed for users.

2 - Includes approximately 4,000 IP ACLs for signaling ports and 100 IP ACLs for OAM. A maximum of 11,232 (for SBC 51x0/52x0 series) and 17,824 (for SBC 5400) IP ACLs are allowed for users.

3 - The number of user-defined ACLs is 772.

4 - The number of user-defined ACLs is 628.

5 - The maximum VLANs supported on SR-IOV VF interface is 64, limiting the maximum number of IP interfaces on the SBC VM with an SR-IOV packet interface to 64.

The time required to add an object to an existing configuration is immaterial (It takes much longer to actually type the command or complete the EMA/EMS fields). However, bulk loading of a large configuration from the CLI may take a substantial amount of time. 

Note
titleCaution

See cautionary note above about the potential bulk configuration loading on call handling performance. 

While the 

Spacevars
0series2
supports large limits on multiple types of configuration objects, a few typical usage scenarios exist. The length of time to bulk load a configuration depends on the size of the configuration. Consequently, four
Spacevars
0series4
profile classes are defined to give customers a rough idea for the bulk loading time relevant to their configuration:

  • 1K profile – comprised of 1,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports, and Trunk Groups
  • 4K profile – comprised of 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports, and Trunk Groups
  • 4K/10K profile – comprised of 4,093 instances of IP Interfaces, 2,048 instances each of Zones, Address Contexts, IP Interface Groups, SIP Signaling Ports, 10,000 IP Peer, and 10,000 IP Trunks (see Note below).
  • 4K/40K profile [SBC 7000 series only] – comprised of 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports; and 40,000 Trunk Groups
Note
titleNote

If both IPv4 and IPv6 are combined on every sipSigPort on an SBC 5200, the system limits the number of sipSigPorts to 1,980.

Maximum CLI Load Times

The following table lists the maximum CLI load times for the above profile classes.

For a system previously loaded with configuration, the start-up time also depends on the amount of configuration. The start-up time is considered the time from when the

Spacevars
0product
application is started (by PM) to the time that the
Spacevars
0product
is ready to accept calls.

Note that this start-up time is typically only relevant to standalone systems after an upgrade. For a HA system, the standby is activated to handle calls while the SBC is being started or restarted.
