Information

 
TitleCaptive portal issues using ExtremeCloud Appliance and external Extreme Control portal
Symptoms
  • Captive portal issues using ExtremeCloud Appliance and external Extreme Control portal
  • Captive portal performance issues
  • XMC Control always seems to resolve the last known address but not the current address
  • The captive portal appears "Frozen" or "Stuck"
  • Issues only appear for 1-2 minutes on initial connection or after VLAN change
Environment
  • XCA 4.56.04 and below
  • Extreme Control 8.3.2 (and lower)
Cause

IP resolution issues between Control and xCA. 

Control does not correctly identify IP Resolution worker being the CtAlias MIB and uses the IpNetToMedia MIB. The IpNetToMedia table is updated slowly, about 1-2 minutes. Any change in IP takes 1-2 minutes to be updated which is too long to initial IP resolution task for new clients, and any IP change due to policy swap will end up returning original IP address as it takes 1-2 minutes to update to new address.

 

RADIUS accounting is supposed to be used as another method of IP resolution, however even if enabled accounting isn't send for unauthorized state. 

Resolution
Issue resolved in Firmware 4.56.05 or higher

Release Note: Corrected issue with offset index for interface ID in CTAlias SNMP table. ECA-734
