[. . . ] Since single IP switch remains its URL of the master switch IP no matter what the agent manager has change the forwarding host, new host will still receive the same authentication key as the master switch when it requests the login authentication. If the new host has the different username and password from the master switch, authentication failure and reentry thus happens. It is strongly recommended that the administrator changes the usernames and passwords of the managed hosts to the same ones as master switch. - 51 - 2. 5. 14. 2 Agent Manager A floating menu will show up after clicking "Launch Agent Manager" in the agent management. The agent manager holds 32+1 slots in the floating menu. The most top slot (zero slot) displays the master switch IP and its relative location. "Remote Agent" means that the user comes from the other IP domain than the managed ones, while "Local Agent", that user comes form the same one as the managed ones. There are differences between "Remote Agent" and "Local Agent". The "Local Agent", we refer to it as "Local Single IP", uses a method like URL link and the main browser window will directly jump to the target host. Since the URL of web browser has change, authentication will request once again when new host is selected. Due to consideration of switch loading, a restriction confines here that only one remote user can access the agent manager in the same time. Other user will be rejected if someone has launched the agent manger first. The switch will release the control of single IP access in 25 seconds after the previous user closes his agent manager. For "Local Single IP", there is no restriction, but if a remote user has launched the agent manager in the same time, the local user is also denied. Note: Commands from agent manager can not pass over current management level, meaning that, in case that a slave host is a single IP switch with its agent function enable, user launch the slave host's agent manager and he/she will find the agent manager is replaced by the slave's one. Much worst, commands to pick the slave hosts will case unexpected forwarding error here. We strongly recommend that a single IP switch should not activate the IP agent manager when it is a slave host of active master switch. - 52 - 2. 5. 14. 3 Stacking Manager After addition of stacking members, press "Launch manager" to pop up the "Stacking Manager". This web UI provides not only the integrated VLAN management, but also a handy IP agent. Administrator can easily access other detail configurations in one individual switch of stacking set by clicking the hostname on the right side of this panel and jumping to its configuration webpage. Link Status The first page shows the current link status of all stacking members. Link-up ports will glow in their port numbers. An off-line switch will dim to gray if it does not respond to the information request from the stacking master in a period of time. This characteristic provides an easy method for network diagnose. Network administrator can check backbones connection of stacking switches at a glance of this panel. VLAN SETUP To configure the VLAN setting of the stacking switch, click "VLAN" to bring up the VLAN configuration panel. - 53 - There are two default VLAN existing in the stacking switches. As seen above, the VLAN name " DEFAULT" and VID " 1" is standard setting for general Tag VLAN , and all port are added as untagged port; The other VLAN " 4091" , as so called " Stacking Tag VLAN" , is an unique setting for this type of stacking. [. . . ] Please refer section 2-4-14 for detailed configuration. Launch the Stack manager. - 135 - 5. 4. 2 An Example of Port-Base Stacking VLAN Port-Base Stacking VLAN setting: Switch: Master (192. 168. 223. 100) Slaves (192. 168. 223. 110, 192. 168. 223. 120, 192. 168. 223. 130, 192. 168. 223. 140, 192. 168. 223. 150) PC: PC-0(192. 168. 223. 99) on port 22 of Master (192. 168. 223. 100) PC-1(192. 168. 223. 92) on port 9 of Slave 4(192. 168. 223. 140) PC-2(192. 168. 223. 93) on port 23 of Slave 5(192. 168. 223. 150) Port-Base VLAN Group: VLAN name : test VLAN ID : 10 Members: Port 22, 24 of Master (192. 168. 223. 100 ) Port 9 of Slave4 (192. 168. 223. 140) Port 23, 24 of Slave5 (192. 168. 223. 150) Test case: 1. PC-0 ping or trace PC-01 and PC-02 ( The same VLAN ) 2. Remove port 9 of Slave4 from VLAN test, and process test1 again. - 136 - Result: 1. [. . . ]
