4. Troubleshooting Communication Failures Due to Resource Shortage [IP8800/S6700] [IP8800/S6600] [IP8800/S6300]1334.2 When Resource Shortage of VLAN IdentificationTable Occurs4.2.1 Checking VLAN Identification Table Resource UsageThis system outputs an operation log message when the usage of VLAN identification table reaches 80% of theaccommodating condition. The operation log message to be output is shown in the table below.Table 4-4: Operation Log Message for Checking Resource UsageCommunication is not immediately affected when the system reached usage of 80%. However, if the VLANidentification table is continuously used by L2 authentication function or the like, the limit of the accommodatingcondition may be reached and resource shortage disabling authentication by the L2 authentication function may arise.Check the set value and accommodation value in advance so that the limit of the accommodating condition will not beexceeded.Check the usage of the VLAN identification table by referring to the manual "Configuration Settings."4.2.2 Action to Be Taken When VLAN Identification Table ResourceShortage OccursWhen usage of VLAN identification table reaches the limit of the accommodating condition, the corresponding logmessage is output at the timing listed in the table below.Table 4-5: Operation Log Message for Checking Resource Use StatusNo. Trigger Log Message1 When VLAN identificationtable use status reaches 80%VLAN classification table entries was beyond 80 percent of capacity.No. Trigger Log Message1 Setting tag translation function - The vlan mapping entry can't be registered at VLAN classification table (VLAN ,port(/)).- The vlan mapping entry can't be registered at VLAN classification table (VLAN ,Channel Group ).2 Setting protocol VLAN - The protocol based VLAN entry can't be registered at VLAN classification table (VLAN,port(/)).- The protocol based VLAN entry can't be registered at VLAN classification table (VLAN,Channel Group ).- The protocol based VLAN entry can't be registered at VLAN classification table (protocol{ethertype | llc | snap-ethertype },VLAN ).- The protocol based VLAN entry can't be registered at VLAN classification table (protocol{ethertype | llc | snap-ethertype },Vlan-Protocol ).3 Setting MAC VLAN static entry - The MAC-VLAN MAC Address entry can't be registered at hardware tables.4 IEEE802.1X authentication(VLAN authentication(dynamic))- The 802.1X Supplicant MAC address of MAC VLAN can't be registered at hardware tables.Note: This log is displayed when the show dot1x logging command is executed.5 Authentication VLAN - The registration of the MAC address failed.Note: This log is displayed when the show fense logging command is executed.6 Web Authentication(Dynamic VLAN mode)- The login failed because of hardware restriction.Note: This log is displayed when the show web-authentication loggingcommand is executed.
