System Manager on the ICS 7750 does not see the chassis

Core Issue

This is an Integrated Communications System (ICS) 7750 with three Service Processing Element (SPE) blades. ICSConfig is unable to discover blades on this chassis. An Error 401 message is reported during the discovery process. Downloading and installing System Manager 2.6.2 has no effect on the 401 error message.


All blades in the ICS chassis must be on VLAN1 for discovery to work. This is the current limitation and there is no workaround.

After enabling VLAN1 and removing VLAN20, all interfaces in ICS are reassigned to VLAN1. After the reboot, everything comes up fine.

This error message can also be displayed due to incorrectly configured    SNMP community strings and DNS misconfigurations. To rule out this possibility, verify that these parameters have been configured correctly.
