XSL 中使用一組不固定資料來判斷另一組資料的輸出值
XML 如下
<?xml version='1.0'?>
<?xml-stylesheet type="text/xsl" href="key_sample.xsl" ?>
</document>
<test id="1" name="a">
<test id="2" name="b">
<test id="3" name="c">
<test id="4" name="d">
輸出結果如下
id=1 value=value1 test name=a
id=2 value=value2 test name=a
id=3 value=value3 test name=c
id=4 value=value4 test name=b

CISCO WS-C3560 IP Source Guard 設定摘要
1.建立 IP Source Guard 使用埠的巨集
建立巨集指令為 switch(config)#macro name macro-name
內容如下：
# macro:oa-clinet
# connect oa network's PC
switchport mode access
# Enable port security limiting port to a single
# MAC address -- that of desktop
switchport port-security
switchport port-security maximum 5
# Ensure port-security age is greater than one minute
# and use inactivity timer
switchport port-security violation restrict
switchport port-security aging time 2
switchport port-security aging type inactivity
# ip source guard
# 確認該介面下MAC所對應的IP位置，是由DHCP所配發，防止用戶隨意更改IP位置
ip verify source port-security
2.建立連接DHCP 伺服器使用埠的巨集
建立巨集指令為 switch(config)#macro name macro-name
內容如下：
# macro:oa-switch
# connect backbone switch
ip arp inspection trust
ip arp inspection limit rate 500 burst interval 3
ip dhcp snooping limit rate 500 // 防止DHCP DOS攻擊，限制Switch轉送DHCP request的速率
ip dhcp snooping trust
3.整體的設定如下：
switch(config)#ip dhcp snooping vlan 1
switch(config)#ip dhcp snooping
switch(config)#ip arp inspection validate src-mac dst-mac
switch(config)#errdisable recovery cause arp-inspection
switch(config)#errdisable recovery interval 3600
4.將交換器上各埠分別套用 1，2 所建立的巨集
switch(config-if)#macro apply macro-name
其他
取消 oa-clinet 巨集的巨集
內容如下
# macro:no-oa-clinet
# remove macro oa-client
# Enable port security limiting port to a single
# MAC address -- that of desktop
no switchport port-security maximum 5
# Ensure port-security age is greater than one minute
# and use inactivity timer
no switchport port-security violation restrict
no switchport port-security aging time 2
no switchport port-security aging type inactivity
no switchport port-security
no switchport mode access
# ip source guard
no ip verify source port-security
no macro description
取消 oa-switch 巨集的巨集
內容如下
# macro:no-oa-switch
# disable oa-switch macro
no ip arp inspection trust
no ip arp inspection limit rate 500 burst interval 3
no ip dhcp snooping limit rate 500
no ip dhcp snooping trust
相關的查詢指令：

CISCO WS-C3560G 忘記密碼，恢復預設值方法
以下方法會失去所有的設定內容
1.拔去電源重新開機。
2.開機完成後，長按前方面板 mode，燈號會開始閃爍，進入重置，自動重新開機。
3.完成開機後即恢復預設。

CISCO WS-C3560G 交換器 NTP 校時設定
1.設定 log 及 debug 訊息的時間戳記
service timestamps debug datetime localtime
service timestamps log datetime localtime
2.設定時區為台灣時區
clock timezone TW +8
3.設定NTP來源的介面來源為 vlan 1
ntp vlan 1
4.指定NTP Server位址，可設定多部伺服器
ntp server 220.130.158.52
顯示 NTP 狀態指令
show ntp status
show ntp associations
其他相關指令
ntp peer // 設定內部NTP設備的IP位址
clock set // 設定時間
show clock // 檢視目前時間
