Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 18
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.
