Description:
This article discusses MTP, traffic and filtering.
Solution:
Typically, MTP may not be able to see traffic for these reasons:
- MTP is not seeing traffic from the switch (via span, tap, aggregator)
- MTP hardware filters are not enabled for TIM logical port or are incorrect (including or excluding subnet for example)
- MTP logical port, ADA, and switch do not have same VLAN tag on both ends (New with MTP/ADA 10)
- CEM Web Filters are excluding traffic
- SSL private keys are not decoding traffic
To Resolve:
- Work with networking team to check switch connection to MTP
- Review MTP hardware filters
- Check that VLAN tagging is correct on MTP and switch and ADA
- Check Web Server filters
- Check Private keys
