4.Troubleshooting Communication Failures Due to Resource Shortage [IP8800/S6700] [IP8800/S6600] [IP8800/S6300]

4.2When Resource Shortage of VLAN Identification Table Occurs

4.2.1Checking VLAN Identification Table Resource Usage

This system outputs an operation log message when the usage of VLAN identification table reaches 80% of the accommodating condition. The operation log message to be output is shown in the table below.

Table 4-4: Operation Log Message for Checking Resource Usage

No.	Trigger	Log Message

1	When VLAN identification	VLAN classification table entries was beyond 80 percent of capacity.
	table use status reaches 80%

Communication is not immediately affected when the system reached usage of 80%. However, if the VLAN identification table is continuously used by L2 authentication function or the like, the limit of the accommodating condition 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 be exceeded.

Check the usage of the VLAN identification table by referring to the manual "Configuration Settings."

4.2.2Action to Be Taken When VLAN Identification Table Resource Shortage Occurs

When usage of VLAN identification table reaches the limit of the accommodating condition, the corresponding log message is output at the timing listed in the table below.

Table 4-5: Operation Log Message for Checking Resource Use Status

No.	Trigger	Log Message

1	Setting tag translation function	- The vlan mapping entry can't be registered at VLAN classification table (VLAN <ID>,
		port(<NIF No.>/<Port No.>)).
		- The vlan mapping entry can't be registered at VLAN classification table (VLAN <ID>,
		Channel Group <Channel Group Number>).

2	Setting protocol VLAN	- The protocol based VLAN entry can't be registered at VLAN classification table (VLAN
		<ID>,port(<NIF No.>/<Port No.>)).
		- The protocol based VLAN entry can't be registered at VLAN classification table (VLAN
		<ID>,Channel Group <Channel Group Number>).
		- The protocol based VLAN entry can't be registered at VLAN classification table (protocol
		{ethertype llc snap-ethertype }<HEX>,VLAN <ID>).
		- The protocol based VLAN entry can't be registered at VLAN classification table (protocol
		{ethertype llc snap-ethertype }<HEX>,Vlan-Protocol <Protocol name>).

3	Setting MAC VLAN static entry	- The MAC-VLAN MAC Address entry can't be registered at hardware tables.

4	IEEE802.1X authentication	- The 802.1X Supplicant MAC address of MAC VLAN can't be registered at hardware tables.
	(VLAN authentication	Note: This log is displayed when the show dot1x logging command is executed.
	(dynamic))
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	- The login failed because of hardware restriction.
	(Dynamic VLAN mode)	Note: This log is displayed when the show web-authentication logging
		command is executed.
