为什么Cisco ios会不按顺序保存和显示访问列表条目？

考虑以下访问列表：

access-list 25 remark city1
access-list 25 permit 10.1.120.0 0.0.0.255
access-list 25 remark city2
access-list 25 permit 10.2.120.0 0.0.0.255
access-list 25 remark city3
access-list 25 permit 10.3.120.0 0.0.0.255
access-list 25 remark city4
access-list 25 permit 10.4.120.0 0.0.0.255
access-list 25 remark city5
access-list 25 permit 10.5.120.0 0.0.0.255
access-list 25 remark mgt
access-list 25 permit 10.3.66.86
access-list 25 remark jumphosts
access-list 25 permit 10.3.1.37
access-list 25 permit 10.3.1.38

如果我按照上述顺序直接将其输入路由器，然后运行“ show ip access-list 25”，列表按以下顺序显示：

Standard IP access list 25
    60 permit 10.3.66.86
    70 permit 10.3.1.37
    80 permit 10.3.1.38
    10 permit 10.1.120.0, wildcard bits 0.0.0.255
    20 permit 10.2.120.0, wildcard bits 0.0.0.255
    30 permit 10.3.120.0, wildcard bits 0.0.0.255
    40 permit 10.4.120.0, wildcard bits 0.0.0.255
    50 permit 10.5.120.0, wildcard bits 0.0.0.255

如果我在运行配置中查看访问列表，则该列表按以下顺序显示：

access-list 25 remark mgt
access-list 25 permit 10.3.66.86
access-list 25 remark jumphosts
access-list 25 permit 10.3.1.37
access-list 25 permit 10.3.1.38
access-list 25 remark city1
access-list 25 permit 10.1.120.0 0.0.0.255
access-list 25 remark city2
access-list 25 permit 10.2.120.0 0.0.0.255
access-list 25 remark city3
access-list 25 permit 10.3.120.0 0.0.0.255
access-list 25 remark city4
access-list 25 permit 10.4.120.0 0.0.0.255
access-list 25 remark city5
access-list 25 permit 10.5.120.0 0.0.0.255

问题：

1）为什么访问列表没有按输入顺序出现？
2）即使未显示也是如此在“显示ip访问列表”输出中以正确的顺序或在运行的配置中，顺序号是按顺序排列的。规则集是否根据序列号或条目的显示顺序进行了解析？
