Scaling limits

[AndrzejP]

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?

>>> 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.


2. 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.)


3. Number of NAPs? I think we heard it's 1024 NAPs.

>>> 1024


4. 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.
