Use non proprietary trunking and no negotiation3. Restrict only to vlans needed 4. SVI on vlan 1 with ip 10.10.10.12 sbnm 255.255.255.05. Configure switch A so that nodes other side of Router C are accessible 6. Make switch B the root 最近813中的LACP实实有部分实化 Distribution Switch (SwitchB) 1) Do not change VTP and STP settings 2) Switch needs to be spanning-tree root for VLAN 11-13,21-23. Other VLAN’s can have default STP priority 3) VLAN’s allowed on the trunk are 1,21-23 Access Switch (SwitchA) 1) STP and VTP settings should be identical to SwitchB2) Configure VLAN’s as per diagram 3) VLAN 1,21-23 needs to be tagged when traversing the link4) No routing needed on SwitchA 5) VLAN 1 needs to be configured with IP – 192.168.1.11/24一.实取实目信息, 1.在SWA上使用sh run, sh vlan, sh cdp nei detail, 确定,. RouterC的ip/SWA的VTP&STP模式/SWA的vlan .SWA的实实端口f0/3,f0/4,f0/15的信息;如trunk, vlan信息, 2.在SWB上使用sh run,sh vlan,sh cdp nei detail,确定 .实实的接口IP～SWA&SWB .SWB的VTP/STP模式～ vlan信息 .SWB的实实端口f0/3,f0/4的信息;如trunk,vlan信息, 二.需求, SWA: 1.SWA: SWA的VTP & STP配置模式不能修改～ 2.SWA:SWA是vlan 1,11-13,21-23的交实机;跟root sw, SWB: 1.增加VLAN21(Marketing),vlan22(sales),vlan23(engineering)2.划分vlan21-23的端口～vlan 21(f0/9-10), vlan 22(f0/13-14), vlan 23(f0/15-16),同实vlan的接入端口实置实portfast 和access模式 3.将SWB的VTP和STP模式实置成和SWA的一致 || 4.SWB上有路由配置～没SWB上有SVI int vlan 1 ip:192.168.1.11/24需要配置 INT SWA-SWB: 1.VLAN 1,11-13,21-23之实的VLAN实实必实无件的实实条trunk模式～在trunk实路上实实实～要打实;所以vlan1要打实～那实vlan1不实实是native vlan,注意实目意实, 2.SWA和SWB之实需要配置成可以最大限度的使用实有实实的模式～必实使用非私有的实实～同实～SWA是主实控制的交实机;initator/activation,3.使用策略限制非必要的VLAN广播 SWB信息 三.实果～成功实志, 1.使用sh eth sum,实实port-channel是否用～实实启状su实表示用正常～启 2.在SWB和SWA上使用sh命令～实实VTP,STP,VLAN信息是否一致 3.SWA是否实交实机跟 4.192.168.1.11,192.168.1.10,192.168.1.1是否可以相互ping通 四,配置～实实步实 1.在SWB上配置vlan信息, VLAN 1～vlan11-13, vlan21-23, vlan98-99～实置root prority 61440,保实SWB实非根交实机 2.在SWA上配置vlan 信息vlan21-23～实置root primary,保实SWA实根交实机 3.在SWB上配置VTP & STP信息～和SWA一致 4.在SWB上端口入将划vlan中～实置接入端口实并access & portfast 模式 5.配置SWB的SVI INT VLAN1 IP:192.168.1.11/24,以及默实实网192.168.1.1 6.SWB和SWA上的F0/3-4口上封装dot1q trunk,并将trunk native vlan修改实vlan99,同实实可vlan1,21,22,23在trunk上打实实行实实7.在SWB和SWA上实置port-channel,使用非私有实实lacp,同实实置SWA实initator---active状实 8.在SWB和SWA上实置port-channel 1 的封装参数 1SWB#conf t ;接入实,SWA#conf t ;分布实, Enter configuration commands, one per line.
