Scaling limits - ProSBC

Hi,

are there any limits on ProSBC:

  1. VLANs assigned to single virtual port. I guess around 4094 is hard limit, but is there any lower limit?
  2. Numer of IP interfaces (and port ranges)?
  3. Number of NAPs? I think we heard it’s 1024 NAPs.
  4. Number of Transport Servers?
  1. VLANs assigned to a single virtual port. I guess around 4094 is a hard limit, but is there any lower limit?

The valid VLAN IDs can be VLAN 0 – 4095, we use VLAN ID 0 to specify the untagged port when doing configuration, and the lowest limit for tagged VLAN is no tagged VLAN, but just untagged VLAN/port.

  1. Number of IP interfaces (and port ranges)?

The standard is 16 (and for the port ranges, the default is 20000-40000, but these values can be adjusted.)

  1. Number of NAPs? I think we heard it’s 1024 NAPs.

1024

  1. Number of Transport Servers?"

standard is 16. (Internally we can achieve up to 96/128)

mentions that TS limit is 96.
Which number is accurate?

We currently have 29 without SAPs, so I guess it’s more then 16.

There is a limit of 16 on the TMG media gateway devices.
On the SBC, we recently increased the limit to 128 SIP transport servers.
