我正在运行EX3300-48T - Junos-12.3R11.2。在同一台交换机的多个vlan上绑定多个/24后，开始发现新旧分配的IP在不同端口的多台服务器上ping不通。
我查了ARP表show arp no-resolve，不是所有的IP都在那里，所以我清理了ARP表clear arp，大部分IP又开始响应了。
# run show arp no-resolve | match entries无论我们做什么，都不会超过4017的限制。
username@juniper# run show arp no-resolve | match entries
Total entries: 3971
然后我搜索了这个范围：192.168.1.0/24，分配给它的服务器宕机了
username@juniper# run show arp no-resolve | match 192.168.1
{master:0}[edit]
然后再次启动服务器，数量上升到相同的限制4017
username@juniper# run show arp no-resolve | match entries
Total entries: 4017
{master:0}[edit]
并且显示了一些IP
username@juniper# run show arp no-resolve | match 192.168.1

它被限制为 4017 的概率是多少？我们不应该期望至少 3971+254=4225 条目，而不是 4017 并且该范围内的其他 IP 应该出现吗？如果是有限的，如何提高？
谢谢，
