In S5700 when configuring voice vlan there is an error says “no enough resources”

Issue Description

In S5700 when configuring voice vlan there is an error said  the device does have

enough resources ,causing that the reset of

25 ports cannot apply the voice-vlan commands, here is the information :

[S5700-GigabitEthernet0/0/22]voice-vlan 302 enable include-untagged

[S5700-GigabitEthernet0/0/22]interface GigabitEthernet0/0 /23

[S5700 -GigabitEthernet0/0/23]undo  voice-vlan 302 enable

[S5700- GigabitEthernet0/0/23]voice-vlan 302 enable include-untagged

Error: This command failed because of no enough resources, please undo it.

From 0/0/1 to 0/0/22 has the same configuration ,the voice-vlan is enabled among

these ports without problem ,but when enable the voice vlan in 0/0/23 ,we can see that

An error popped out  “Error: This command failed because of no enough resources, please undo it.”

Solution

According to the configuration in the S5700, there are 46 OUI configured

voice-vlan mac-address 8483-7100-0000 mask ffff-ff00-0000 description avaya

…

voice-vlan mac-address 0015-6500-0000 mask ffff-ff00-0000 description yealink

voice-vlan mac-address 8cb6-4f00-0000 mask ffff-ff00-0000 description cisco

voice-vlan mac-address e468-a300-0000 mask ffff-ff00-0000 description huawei

…(total 46 items)

If each port configured the  “voice-vlan 302 enable include-untagged” , it will take up 46 ACL ,and the

total vlan ACL resources for this switch are 1024 ,

So only the front 22 port can configure this command without any error ,because 22*46=1012 ,if continue

the same in port 23 , It is not enough  since the rest

resources are  only 12 , that is why the device show an error ; the solution is to aggregate the OUI or select

the OUI that is only match the vendor’s IPPHONE

which are connected to Switch only ,because in customer site ,it is impossible to have more than 40 vendors’ IPPHONE.
