Lucent Technologies P220, P550R manual Snmp, Spanning Tree

SNMP

NOTES:

•Cold start traps cannot be transmitted out of inband interfaces when Spanning Tree is enabled.

•ipAddrTable does not display inactive interfaces (VLANs). An inactive interface occurs when there are no active ports on a VLAN.

•You cannot have more than 10 SNMP community strings per switch.

Spanning Tree

NOTES:

•The Cajun P550 48-port Media Module (M5548E-100TC) supports Spanning Tree for each group of eight ports at the internal switch port. Spanning Tree functionality is disabled by default. If per-port STP is required, it is recommended that you use a Cajun P550 20-port Module (M5520-100TX) or Cajun P550 Layer 3 12-port Copper Module (M5512R-100TX).

•Release 4.0.1 does not allow modification of the Spanning Tree and Fast Start features on the CPU switch port. When you modify all switch ports, the Spanning Tree and Fast Start features will be not be applied for the CPU switch port and the corresponding status line does not display.

•Spanning tree convergence may take longer than 30 seconds in complex networks after a topology change

Problem: When IEEE 802.1D spanning tree is used with hunt groups, the non-flood ports are shown as forwarding, even if the hunt group is blocked.

Workaround: The flood port of the hunt group shows the actual state of the spanning tree. View the flood port to see the actual state of the spanning tree.
