Trunk on the corresponding port of the 6509 and Annette Switch connected to the optical transceiver, the Annette switch is divided into two VLANs, respectively 172.25.6.0/24 (hereinafter referred to as VLAN6) and 172.25.7.0/24 (hereinafter referred to as VLAN7), The machines of the two departments are connected to their respective VLANs. The convergence layer
A strange problem occurs in the VLAN of the two Departments in the office area of the organization. Some websites on the Internet can access normally, but some websites cannot access it. emails received through Outlook or Foxmail are normal, it is also normal to send small emails without attachments, but it cannot be normally sent when sending large emails or emails containing attachments. Internet access is normal in other office areas of the Organization. The topology 1 of this part of the net

1. Los: Alarm for signal lossIt indicates that the local end cannot receive light or electrical signals. When the signal amplitude remains below a preset threshold value (the threshold value is very small, far lower than or equal to 10-3) within a given time (for example, 100 ms, the SDH device enters the Los state. If two consecutive valid frame locating patterns are detected and no los is detected, the SDH device should exit the Los state.(1) optical port los:Network Management alarm: Light re
There are two modules for restricting IP connections and concurrency:Click the hyperlink below to view the official details of the corresponding module
Limit_req_zone is used to limit the number of requests per unit of time, which is the rate limit
limit_req_conn is used to limit the number of connections at the same time, the concurrency limit

If you want to store the partition in a particular tablespace, you can do so by using the store in clause:
Interval (numtoyminterval (1, ' MONTH '))
Store in (par01,par02,par03,par04,par05,par06,par07,par08,par09,par10,par011,par012)
This clause stores the partitions in the Tablespace TS1, TS2, and TS3 in a circular manner.
Such as:

particular variable (null values will not be considered). $variable defines the key, Zone=name defines the name of the zone, and the following limit_conn instructions are used. Size defines the amount of shared memory space for each key. Such as:
Limit_conn_zone $binary _remote_addr zone=addr:10m;
Note: The IP address of the client is the key. Note that the $BINARY_REMOTE_ADDR variable, not the $REMOTE_ADDR variable, is used here.$remot
versions, due to removing the concept of permanent generation, therefore, the memory layout is slightly different.
The following is an example of code to implement memory overflow in a constant pool:
