思科交换机C4503死机问题~

yagamixp

核心交换机思科C4503在使用过程中平均20天左右就会出现死机情况,其死机时出现下情况:(从2006年购入开始,配置文件无问题)
        1,交换机变成普通交换机况态,仅可以通讯,但是VLSM出现问题(公司由于PC机比较多,所以网段为192.168.100.0/23),192.168.101.X/23的机器无法与192.168.100.X/23的机器通讯.
        2,交换机telnet无法连上,但ping正常,console连接上可以看到报错日志,但无法配置及敲入命令,仅可以看到跳动的日志信息.
        3,ACL的规则正常,VLAN规则正常
        4,在远程日志服务器上出现最后两条错误信息就不在发送日志信息
        5,核心交换机时间不走,这是在交换机重启后发现交换机时间停在上次死机时时间上
    B)如出现以上情况,须要把交换机电源完全断开后,重启启动完,核心交换机又回复正常工作
        1,交换机所有工作正常,子网间正常通讯
        2,telnet可正常连接,console连正可正常使用
        3,交换机时间须重新设备,因为它的时间是从上次死机时开始
    C)远程日志服务器上最后几条日志信息如下:
Nov 13 16:42:46 192.168.100.254 1041: .Nov 13 16:39:31: %C4K_EBM-4-HOSTFLAPPING: Host 0C:77:1A:E1:1B:F3 in vlan 20 is flapping between port Gi1/12 and port Fa2/46

(排除IP冲突,从最后两条信息出现后就再也没有信息过来)
     D)console日志,除ACL外错误信息如下:(比较多,大约10-20秒一次这个错误,同时不可操作仅在介面出现信息)

有没有升级过IOS？内存不够吧

经过与厂家技术支持后,应该是内存有问题,厂家说只能换引擎板才能解决此问题.
