HomeDatabaseMysql Tutorial华为MA5200F无法创建PORTVLAN的问题

在郑州培训单位的工作也不能少,唉~命苦

在郑州培训单位的工作也不能少,唉~命苦啊。
要开通一个华为的小型DSLAM,E100,96线的那种DSLAM设备。需要在BAS上做数据,可是在添加数据的时候出错了:
 
[a-b1]portvlan ethernet 4 vlan 500 100
[a-b1-ethernet4-4-vlan500-599]access-type layer2
 %Only 13 more portvlan can be used
 
提示还有13个portvlan可以使用,晕~~以前从来没有见过这种错误,上GOOGLE查了查。是这样说的:
-----------------------------------------------
由于Portvlan的数量达到版本限制导致MA5200F无法新添加Portvlan

现象描述:
从提示信息来看是由于portvlan的资源已经被用尽,所以再添加新和portvlan时系统提示“0个portvlan可用”,添加失败。
告警信息:
1、查了一下MA5200F整机最多允许配置8K个portvlan。
2、查看当前的数据配置,发现已经配置了8K个portvlan(计算方法为把所有端口下配置的vlan相加即可,如portvlan ethernet 1 vlan 1 100,表示配置100个portvlan),客户人员在配置数据时,没有根据实际的VLAN的分配而配置,而是在每个端口下配了一个很大的VLAN段,从而导致portvlan被大量占用。
3、与客户确认删除了不必要的portvlan数据后,问题解决。
原因分析:
在数据配置时要尽量根据实际的情况来配置数据,不然的话会造成资源的浪费,以及数据配置中存在大量的垃圾数据。
------------------------------------------------------
以前只是知道BAS的一个端口最多可以配置4K的VLAN,还不知道BAS整机对于VLAN还有限制,复核了一遍BAS上的数据,确实整机的VLAN配置到了8000多。开来要删除一些垃圾数据了。
以前的同事在配置VLAN的时候,总是给一个机房多一点的VLAN资源,看来以后不能这样做了,需要多少配置多少,不然以后有的麻烦了。

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient.
